Frequently asked questions

Yes. Every tool on this site works in your browser with no account and no sign-up, and nothing is charged.

No. OnePDF runs inside your browser, so your files are opened, edited and converted on your own device. A copy of each file you open is kept in this browser so you can reopen it from Recent; you can remove it at any time.

Yes. Click any paragraph to retype it in the document's own font, or drag it to move it. Run OCR first to edit a scanned page.

PDF to Word (.docx), Excel (.xlsx), PowerPoint (.pptx), JPG, PNG, plain text and Markdown, and Word, Excel (.xlsx, .xls, .ods), PowerPoint, JPG, PNG, text and Markdown to PDF.

Yes. Text comes out as real Word paragraphs and runs, not pictures of text, so you can retype, restyle and reflow it.

Close to it. A PDF records where each line was drawn, not how the document was built, so the layout is rebuilt from the page. Fonts you do not have are replaced by Word with similar ones, and drawn lines and shapes are left out; the converter tells you when it leaves something out.

Yes. Open it, run OCR from the tools list to recognise its words, then convert. Without OCR a scanned page comes across as a picture.

Yes. The result is a standard .docx file, which Word, Google Docs, Pages and LibreOffice all open.

Yes. It looks at where every word sits: the gaps down the page become columns and the lines become rows. Text outside tables comes across too, a line per row.

Yes, when they read as numbers. A code with a leading zero, like 007, stays text so it is not changed, and an amount with a currency sign stays as written.

Run OCR first so the words are recognised, then convert to Excel.

Yes. Text is in real text boxes and pictures are real pictures, so everything can be moved, restyled and retyped.

A presentation has one slide size, so pages of another size are scaled to fit and centred. The converter says when it does this.

Rectangles and straight lines are. Curves and freehand drawings are left out, and the converter tells you when it does.

144 dots per inch, so an A4 page comes out about 1190 × 1684 pixels.

JPG makes smaller files and suits photos and scans. PNG is lossless and keeps text and line drawings perfectly sharp. Both are in the Convert panel.

PNG keeps text, charts and line art perfectly sharp. JPG files are smaller and better for photographs.

Pages are drawn at 144 dots per inch, twice the size they appear on screen at 100%.

Yes, once the scan has been recognised with OCR. Without OCR a scanned page has no text to extract, and the converter says which pages those are.

Headings, bold and italic text, bulleted and numbered lists, and text that sat side by side as tables. Fonts, colours and positions are not part of Markdown.

Any .docx, the format Word has saved since 2007. For an older .doc, open it in Word, save it as .docx, then convert.

Your document's fonts are used when this device has them. Otherwise the nearest face of the same kind (serif, sans-serif or monospace) is used, and the converter tells you which fonts were replaced.

Not yet. Body text, tables, lists and pictures are; the converter tells you when a document has headers or footers it left out.

.xlsx, .xlsm, .xlsb, the older .xls, and OpenDocument .ods.

Values are shown the way Excel's General format shows them, and dates as year-month-day. Cell colours, borders, fonts and charts are not carried yet, and the converter says so.

No. A PDF has no animations, and speaker notes are not printed on slides.

Not yet. Charts and SmartArt diagrams are left out, and the converter tells you how many.

Yes. Select all of them at once and each becomes a page of the same PDF.

Yes. After converting, run OCR from the tools list to recognise the text.

No. PNG images are embedded without recompression. Use Compress afterwards if you want a smaller file.

Yes. Choose both kinds together and each becomes a page.

Yes. Headings, bold, italic and lists in .md and .markdown files are typeset.

Yes. Write it here and press Create PDF: OnePDF sets the pages in your browser. Nothing else is needed.

Yes. Insert a picture from your device, or a table with as many rows and columns as you need. Both are kept in the PDF.

Yes. Choose Blank pages, how many and what size, and the empty PDF opens in the editor for you to add text, images, shapes or a signature.

Yes. Click any paragraph to retype it where it sits, and drag it to move it.

Yes. New words are set in the document's own embedded font, with its size, weight, colour and spacing.

Yes. Run OCR from the tools list; the recognised words can then be edited like any other text.

No. Open a file and start editing: no tool needs an account. Sign in with a TensorActivity account if you want your files kept for you, on every device you sign in to.

Yes. Click it to retype or restyle it, or drag it somewhere else.

Yes. Added text sits on top of the scan like on any other page.

Yes. They are standard PDF annotations, shown by Adobe Reader, browsers, Preview and every other reader.

Yes. The All comments page lists every comment and mark in the file.

JPG and PNG, including PNGs with transparency.

Use Add text to type anywhere on the page, and Sign to add your signature.

Yes. Draw your signature, place a signature image, or sign with a certificate from the Sign page.

A drawn signature is a picture of your handwriting on the page. A digital signature is cryptographic: PDF readers can check who signed and whether anything changed afterwards.

Only for a digital signature. You can use one issued to you, or create a self-signed one on the Sign page. Drawing a signature needs nothing.

Not unless you sign in. Signed out, your file is opened by OnePDF inside your browser, on your own device, and is not uploaded to any server. Signed in with a TensorActivity account, the files you open are also saved to your account, encrypted, so they are there on every device you sign in to. Your certificate and its password are never uploaded, signed in or not.

Yes. The text and pictures under each box are deleted from the page, and the file is rebuilt so no earlier revision still holds them.

Before you apply it, yes. Marks can be removed from the list. After applying and saving, the content is gone for good.

Not unless you sign in. Signed out, your file is opened by OnePDF inside your browser, on your own device, and is not uploaded to any server. Signed in with a TensorActivity account, the files you open are also saved to your account, encrypted, so they are there on every device you sign in to. That matters most for a document you are redacting: signed in, the file is saved to your account as you open it, unredacted, and replaced by the redacted file when you save. To keep the original out of your account, redact it signed out, or choose "Keep on this device only" for it.

Yes. Choose a PNG or JPG; transparent PNGs work best.

A watermark added here can be removed again with OnePDF before or after saving.

Yes. Set the first number, and choose which pages to number.

No fixed limit, only your device's memory. Merging happens on your computer, not a server.

Yes. Move files up and down in the Merge list before merging, and pages in the Pages panel afterwards.

Type a range like 2-4 and save it, or use Extract pages.

Text and vector drawings keep full quality at every level. Pictures are scaled and recompressed more at Balanced and Smallest.

If a level would not make it smaller, the file is left exactly as it was, and you can try a stronger level.

Yes. It is saved in the file, so every reader shows the page turned.

Yes, with Undo, until you save. After saving, open the original file again.

Yes. Use Merge PDF to add other files, then reorder their pages here.

They are the same tool: Extract saves the ranges you type, Split can also save every page as its own file.

It cannot be recovered; that is what makes it secure. Keep it somewhere safe.

Yes. Open the PDF with its password and remove it in the Password panel; see Unlock PDF.

No. You need to know the password to open the file; OnePDF then saves a copy without it.

About 50: English, Chinese, Japanese and dozens of Latin-script languages such as French, Spanish, German and Portuguese. The models suited to your browser's languages are chosen for you. Letters with dots below them, as in Yoruba, are not recognised yet.

No. The recognition models run in your browser, on your own device: text recognition never uses a server, signed in or not.

Yes. Once the words are recognised, PDF to Word, Excel and text all use them.
