I need to remove a watermark from a PDF, but I’m stuck on my phone and can’t install anything. I tried a few online options and they didn’t work well. Any advice?
Honestly, the easiest thing to check first is Sejda in your mobile browser. If it is a proper text watermark you can just tap and delete it, though it wont work if the whole file is a flat image scan.
If it is your document or you have permission, try a browser-based PDF editor with a “remove watermark” tool. If the watermark is baked into a scanned page, it usually cannot be removed cleanly; on a phone, OCR the text and export a new PDF instead. Avoid uploading invoices containing sensitive information unless you trust the service.
