Frequently asked questions

Yes — every tool here is completely free, with no limits, watermarks, or account required.

No. This tool runs entirely in your browser, so your files never leave your device.

No installation and no sign-up. It works in any modern browser on desktop or mobile.

No. The tool is free; you bring your own AI provider key and pay that provider directly for what you use — never us.

Your text is sent straight from your browser to the AI provider you pick, using your key. We don't proxy, see, or store it.

Translation quality depends on your chosen AI model, which supports a wide range of major languages. Pick the target language before you run it.

This translates the text content. Complex original layouts aren't reproduced exactly — the focus is accurate, readable translated text.

It generates study and quiz questions drawn from the document's content, each with an answer, so you can test your recall.

The tool is free; you only pay your own AI provider for the usage on your key.

Invoices, receipts, and forms with clear fields — vendor, dates, line items, and totals — extract most reliably into clean, structured data.

You can download the extracted fields as CSV for spreadsheets or JSON for feeding into other tools.

Yes. The CSV export uses a simple front,back format that both Anki and Quizlet accept directly.

There's no fixed limit. Because merging happens in your browser, the practical ceiling is your device's memory — dozens of ordinary documents combine without trouble.

Yes. The output follows the exact top-to-bottom order of the file list, so drag the files into place before you merge.

Page content, text, and images are preserved. Interactive elements like bookmarks and form fields may not carry across all files; flatten a form first if you need its filled values baked in.

Enter page ranges like 1-3 or 5,8-10 to pull specific sections, or choose the option to split every page into a separate one-page PDF.

When a split produces more than one PDF, the results are packaged into a single ZIP so you can download everything at once. A single range downloads as a plain PDF.

Yes. Drag thumbnails to rearrange them and remove the ones you don't want — then save once to get a single clean PDF with all your changes.

No. Pages are moved intact, so text stays selectable and images keep their original resolution.

Yes. The new orientation is written into the saved PDF, so it displays and prints the right way up in any viewer.

This tool rotates the whole document at once. To turn a single page, use the Organize tool, which lets you act on individual pages.

The download is a new file with those pages removed; your original stays untouched on your device, so you can always start over from it.

No — remove as few or as many as you like, as long as at least one page remains in the document.

Extract pulls the pages you pick into one new PDF. Split breaks a document into several files by range. Use extract when you want a single tidy subset.

No. You get a new PDF with just the selected pages; the file on your device is left exactly as it was.

Yes. Choose to insert after any page number, so new pages land exactly where you need them.

No — pages from a second PDF keep their own size. Blank pages are created to match the surrounding document.

Page numbers are applied across the document; if you need to skip a cover page, remove it first with Delete Pages, number the rest, then reinsert the cover.

Numbers sit in the margin at the position you choose, so on standard documents they stay clear of the body text.

A page-identification scheme used in legal and business documents: each page gets a unique, sequential identifier (often a prefix plus a padded number) so any page can be referenced unambiguously.

Yes — set the starting number to wherever the last batch ended, and keep the same prefix and digit count.

The tool alternates for as long as both files have pages, then appends whatever remains of the longer file, so no page is lost.

You can add new text, drawings, and highlights on top of the page. Rewriting the original embedded text isn't supported — PDFs aren't word processors — but you can cover and annotate freely.

No. Editing happens entirely in your browser, so the file and your changes stay on your device until you download the result.

Yes. The viewer renders your PDF in the browser so you can read and zoom immediately, and the file never leaves your device.

Yes — the viewer is responsive and works on phones, tablets, and desktops.

This tool works with interactive (AcroForm) PDFs. If a form is just a flat scan with no real fields, use the Edit tool to type text directly onto the page instead.

Yes. Turn on flatten before saving to bake your entries into the page so they can't be edited.

Yes. Set the crop box once and choose to apply it to all pages, or crop just the page you're viewing.

Cropping hides the area outside the box from view and print. For content that must be permanently destroyed, use the Redact tool instead.

Yes. Lower the opacity to place a subtle watermark behind your content, or raise it for a bold, unmistakable stamp.

Yes, the text is applied to all pages so the whole document is marked consistently.

Flattening bakes form fields, comments, and stamps into the page so they can't be changed and always display the same way — useful before sharing a completed form.

No. Once flattened, the interactive fields become static content. Flatten only after you've entered your final answers.

No. Pages are scaled proportionally to the new paper size, so text and images keep their aspect ratio.

When a document prints on the wrong paper size, or a portal requires a specific size like A4 — resizing brings every page to the size you need.

PDFs often carry hidden details — the author's name, the software used, creation dates — that you may not want to share. Stripping metadata before sending a file removes that trail.

No. It uses the text-to-speech voices already built into your browser and operating system, entirely offline-capable and free.

Voices come from your operating system. Most devices include several; installing extra system voices makes them available here too.

No. Captures go straight from your camera into the page in your browser, the PDF is built locally, and nothing is ever uploaded.

Yes — after saving, run the result through the OCR tool to add a selectable, searchable text layer.

Headings, paragraphs, and lists carry over cleanly. Very complex layouts, embedded objects, and exotic fonts may render slightly differently since the conversion runs in the browser.

This tool reads the modern .docx format. Open an older .doc in Word or Google Docs and save it as .docx first.

This is a text-focused conversion: paragraphs and headings carry over cleanly, but complex layouts, columns, and images are not reproduced. It's built for getting editable text out fast, not pixel-perfect layout.

Scanned PDFs contain images, not text. Run the PDF through the OCR tool first to add a text layer, then convert it to Word.

Yes. Add any combination of JPG and PNG files; each becomes one page in the finished PDF.

Drag the images into the order you want before creating the PDF — pages follow that order top to bottom.

Pages are rendered at a high resolution suitable for sharing and printing. A single page downloads as a JPG; multiple pages are bundled into a ZIP.

This tool exports JPG, which keeps file sizes small. If you need transparency or lossless images, extract embedded pictures with the Extract Images tool.

No. Text recognition runs in your browser via WebAssembly. Only the recognition model files are fetched (once, cached); your PDF and its text never leave your device.

Yes. Each page is kept as its image, and a selectable text layer is placed invisibly on top — so it looks identical but is now searchable.

Scanned PDFs are images of text, not real text. Run the file through the OCR tool first to add a text layer, then extract.

It extracts the raw text, so paragraphs carry over but complex layout, columns, and styling do not. For an editable document, use PDF to Word.

Images are saved in their embedded format (typically JPG or PNG). Multiple images are bundled into a ZIP for a single download.

Only true embedded raster images are extracted. Vector graphics and text drawn on the page aren't images, so they aren't pulled out.

Cell values are laid out as a clean table; live formulas are shown as their calculated results. Heavy styling and charts aren't reproduced — the focus is a readable table.

Yes. Both Excel (.xlsx) and comma-separated (.csv) files are supported.

Yes. Line breaks are preserved and long lines wrap automatically so nothing runs off the page.

Standard UTF-8 text files work best, covering most languages and common symbols.

It depends on the file. Scanned and image-heavy PDFs often shrink dramatically; documents that are mostly text are already small, so gains are modest. If compression wouldn't help, the original is kept.

Higher-compression settings reduce image detail to save space; choose a gentler level to keep pages crisp. Text stays sharp either way.

Pages are re-rendered as grayscale images to guarantee a faithful result, so text is no longer selectable. If you need selectable text afterwards, run the result through the OCR tool.

Yes. In Content mode each file is a standard, multi-page PDF with a cover page plus sections of selectable text — you can open, search, and extract it like any document. Blank mode gives you empty pages instead. For larger sizes the exact byte count is reached by adding harmless padding inside the file.

Presets run from 50 KB to 100 MB, and you can enter any custom size up to 200 MB. Everything is built locally in your browser — nothing is uploaded.

No. The PDFs are generated on your device and never sent to a server.

There's no recovery — the file is genuinely encrypted. Store the password somewhere safe, because we never see it and can't reset it.

The PDF is encrypted with a standard cipher so it can't be opened without the password, while still opening normally in any PDF reader once the password is entered.

It places a visible signature image on the page, which is fine for most everyday agreements. It is not a cryptographic digital signature (PKI) and does not provide certificate-based identity verification.

No. The PDF is signed entirely in your browser — your document and signature never leave your device.

No. Unlock only removes protection when you supply the correct current password — it's for documents you own, not for bypassing security.

No. The password is used locally in your browser to decrypt the file, and nothing is uploaded.

Yes. Any page you draw a box on is rasterized (flattened to an image) before download, so the text and content beneath your black boxes are gone — not just visually covered.

No. Redaction happens entirely in your browser; your document never leaves your device.
