Frequently asked questions

Did not find your answer? Ask on Telegram.

Is it free to edit a PDF here?+

Yes. PDFs up to 50 MB can be edited for free. There is no account and no login.

Is my file safe?+

Your file is used only to make the edited PDF and is deleted automatically after 2 hours. Press "Delete files" on the download page to remove it right away.

Will the font change when I edit text?+

No. The font already used in the PDF is reused. If a letter is missing from that font, a close match is used for that letter only.

Can I edit a PDF on my phone?+

Yes. Open the site in the browser on your Android phone or iPhone. Long documents are easier on a laptop.

Can I change the text of a scanned PDF?+

No, a scan is a picture. You can still add text, images, a signature or a whiteout box on top of it.

Do I need to download an app?+

No. Everything runs in the browser: Chrome, Edge, Firefox or Safari.

Can it merge, split or compress PDFs?+

Not yet. The editor handles text, signatures, forms, images and pages (rotate, remove, insert blank pages).

What if I make a mistake?+

Press Undo or Ctrl+Z. Redo is Ctrl+Shift+Z.

Does it cost anything?+

No. PDFs up to 50 MB can be edited for free, without signing up.

Can I edit a PDF on my phone?+

Yes. Open the site in your phone browser and upload the file. Long documents are easier on a laptop.

Can I edit a scanned PDF?+

A scan is a picture of a page, so its words cannot be changed. You can still add text, images and signatures on top of it.

Why does my edit look slightly different?+

Many PDFs only carry the letters they use. Letters that are missing come from a similar font. You can also pick another font from the Fonts menu.

Can I add a line in the middle of a paragraph?+

Yes. Click where you want it and press Enter or Shift+Enter.

Will it work on any PDF?+

It works on PDFs with real text, such as files saved from Word, a browser or billing software. Scans and photos cannot be rewritten.

Is this a legally binding signature?+

The tool places an image of your signature on the PDF. It is not a certificate-based digital signature. Where a certified e-signature is required, use a service built for that.

Can I sign on my phone?+

Yes, you can draw your signature with your finger on the phone screen.

How do I know if my form has fields?+

Fillable fields are highlighted after you upload the PDF. If none show up, use the Text tool to type on the page.

Can others change what I filled in?+

Real form fields stay editable, so check the form before you send it.

Can I type in Hindi or other Indian languages?+

Yes. If a character does not show correctly, pick a font such as Noto Sans from the Fonts menu.

Can I change the text later?+

Edit it as often as you like before "Apply changes". After downloading, open the new PDF in the editor again to change it.

Which image types work?+

Common formats such as JPG, PNG and WEBP.

Can I remove an image that is already in the PDF?+

Yes. Choose "Delete image" in the Images menu and click the picture.

Does whiteout delete the text for good?+

No. Whiteout only covers it; the words underneath stay in the file and can still be copied. Do not rely on it to hide passwords or bank details. To replace words, use "Change Text in PDF", which removes the old text.

Does it work on scanned PDFs?+

Text cannot be selected on a scan, so use the highlight box, which works on any area.

Can I reorder pages?+

Not yet. You can rotate pages, remove them and insert blank ones.

Does rotating reduce quality?+

No. Only the page orientation changes; the content is not redrawn.

Can I edit someone else's invoice?+

Only edit invoices that you issued or have the right to change. Altering someone else's invoice, receipt or bill and using it is fraud and against the law.

Does the total update itself?+

No. A PDF does not calculate, so update the total yourself after changing rates or quantities.

Can I set the tab order?+

Yes. Use "Tab order" in the Forms menu to decide which field comes next when someone presses Tab.
