Pick a preset (Light = quick, modest savings · Balanced = sensible default · Strong = aggressive image rasterise) or aim at a target size in KB. Lowering the image DPI cap is the biggest single knob.
Drop all the files, drag them into the order you want, then merge. The result is a single PDF with everything stitched together in order.
Either every page becomes its own file, or you specify ranges (e.g. 1-3, 4-7, 8). You'll get a zip with each piece inside.
Apply the rotation to every page (type all) or just the ones you list (e.g. 1, 3, 5-8). Useful for fixing scans that came out sideways.
Type the page numbers to delete (e.g. 3, 5-7, 12). Everything else stays put. Originals are not touched — you get a new file back.
The opposite of delete. Type which pages you want (e.g. 1-3, 7) and you get a fresh PDF with just those.
Pick the format (PNG or JPG) and DPI. You'll get one image per page, zipped up. Useful for previews, sharing snippets, or feeding pages into other tools.
Drop the images in the order you want them, pick a page size, and you'll get one image per page. Great for turning scans or photos of pages back into a document.
Works on PDFs that already contain text (most modern ones). Does not OCR scanned PDFs — if the page is just an image of text, no text comes out.
Choose a password and the file can't be opened without it. Encryption uses AES-128. Don't forget the password — there is no recovery option.
Type the current password and the encryption is lifted. This only works if you actually know the password — it isn't a cracker.
Pick the text, the angle, the opacity, and the size. The watermark is drawn over each page in a single pass.
Pick the position (corner or center, top or bottom), the font size, and the starting number. Useful for printable handouts.
