Use the redeem button on your AppSumo purchase page. You'll land on Featherlight and the device you're on turns Pro straight away. There's no account and no password. On another device, open Activate Pro and paste the same license key.
2 on Pro, 5 on Pro Plus, 15 on Pro Max. Each browser counts as one device, as does the Windows app.
Activate it with your key. If you're at your limit, the activation page lists your devices: remove the old one and the new one turns on. You can remove up to 3 devices every 30 days yourself; email us if you need more.
Yes. Each device carries a license good for 30 days that renews by itself whenever you're online, so a trip or a dead connection changes nothing.
Activation links only work once. Go back to your AppSumo purchase page and open it again to get a new one.
No. Your devices move to the new plan by themselves the next time each one is online.
Nowhere. They open, change and save on your own device, including when you run OCR, compression or flattening.
Firefox and Safari don't let web apps write to files directly, so you get a downloaded copy. Chrome and Edge can save straight back to the original file.
Yes, once you've opened it online and installed it from your browser's install option. Anything that runs on your device keeps working, including Pro on a device you've activated. OCR downloads a language's data (a few MB) the first time you use that language; after that it works offline too.
In your browser, on that device. They aren't sent to us, which also means they don't follow you to another device and clearing your browser data removes them.
As many as you like. They run on your computer, so there's no monthly limit. Your plan sets how many devices one license covers: 2, 5 or 15.
It depends on your computer. On a 2018 laptop a dense, full page of text takes about 4 to 5 seconds, and several pages are read at once. A 20-page scan usually takes a minute or two.
English, Dutch, German, French, Spanish, Italian, Portuguese, Polish, Czech, Swedish, Danish, Norwegian, Finnish, Turkish, Russian, Ukrainian, Arabic, Hindi, Chinese (Simplified) and Japanese. You can combine two languages for a mixed document.
Yes, one line at a time (Pro). Switch to Edit, click a line, type and press Enter; Esc cancels. Leave the line empty to erase it. Click an edited line again to change it, or press Original to put the old text back. Edits are written into the page when you save.
What to expect: the new text keeps the line's position, size and colour, but is drawn in the closest standard font (Helvetica, Times or Courier), so it can look slightly different from the original typeface. Longer text doesn't push the rest of the paragraph along. The standard fonts cover Western European languages; other scripts are refused with a message rather than saved as empty boxes. The old line is covered, not removed: anyone can still copy or search it out of the file. Don't use Replace text to hide confidential information.
All three are in Edit (Pro). Image places a PNG, JPEG, WebP or GIF on the page you're looking at; drag it to move it, drag the corner to resize it, and press Delete or Remove to take it off. It's written into the page when you save, and transparent areas stay transparent.
Watermark writes text across the middle of each page you choose, at the size, colour, opacity and angle you pick. Page numbers offers "1", "Page 1", "Page 1 of 10" or "1 / 10" in any corner or centred, from any start number, on any range of pages (for example 2-end to leave the cover unnumbered). Both are applied straight away and Ctrl+Z takes them off again until you save. Rotated pages are handled as you see them: the number sits at the bottom of the page as displayed.
In Edit (Pro), use Mark text to mark every place a name or number appears, including inside form fields, or Redact area to drag boxes over anything else, such as a signature or a photo. Check the marks, then press Apply redactions.
What happens: each marked page is turned into a picture of itself with the marks painted black, and the page's text, fonts, comments and form fields are deleted from the file, not hidden. Form fields from those pages leave the form, the hidden text structure used by screen readers is removed, and by default the title, author, subject and keywords are cleared too. The rest of a redacted page can no longer be selected or searched; run OCR afterwards if it should be. Ctrl+Z brings everything back until you save. After saving it can't be undone. Saving with marks you haven't applied asks first, because the text under them would still be in the file.
Mark text finds text inside one line. A name split across two lines needs Redact area, and so does a scan that hasn't been through OCR. Always look the marks over before applying.
Drop the images on the start screen, or pick them with Open files (Pro). Put them in order, choose A4, Letter or "same size as each image", and press Create PDF: one page per image, opened as a new document for you to save. Phone photos are turned the right way up, and a page turns landscape for a landscape picture. PNG, JPEG, WebP, GIF and BMP work.
Use the Export as images button in the top toolbar (Pro). Pick PNG (sharp text) or JPEG (smaller, for photos), 72, 150 or 300 dpi, and the pages. One page downloads as an image, several as a zip. Comments, filled fields, signatures and edits you haven't saved yet are included, exactly as they'd be printed.
Featherlight places visual signatures, without digital certificates or audit trails. That's usually what's expected for everyday sign-and-return paperwork, but check if your document has stricter rules.
It's probably an XFA form, an older Adobe format that opens view-only. Standard PDF forms work.
It's on your AppSumo purchase page. On a device that's already Pro, the license menu shows its last characters.
