What happens
4What happens, and why
Drop a PDF and every page comes back as a PNG, listed in order with a download next to each. The one choice is the resolution — 150 dpi for a screen, 300 for print — and the images are drawn again when you change it.
PNG suits what PDFs mostly hold: text, tables, diagrams, line art. It stores the drawn page without loss, so the edges of letters and lines stay exactly as they were drawn, with none of the blocks or haze a JPEG leaves around them. The cost is size: a page of text is usually a few times larger as a PNG than as a JPG, and a page full of photographs much larger.
The badge still says the page was saved again, and it has to. A PDF page is a list of drawing instructions, not a picture; the PNG keeps every pixel of the drawing, but the drawing itself is new — made here by PDF.js, the renderer inside Firefox, at the resolution you chose. Text becomes pixels: it looks the same and can no longer be selected or searched.
Pages are drawn on white with their own rotation, form fields and notes included. A page larger than 16.7 million pixels at the chosen resolution is drawn at the largest one that fits, so it still opens on a phone, and the note says so. Nothing is uploaded: the file is read in this tab and the images are written here.
FAQ
5Is the background transparent
No, white. A PDF page has no background of its own and every reader shows it on white, so that is what the image shows. A clear background would show whatever sits behind the image wherever you put it, which is rarely how a page should look.
PNG or JPG
PNG for pages of text, tables and drawings — the edges stay crisp and nothing is lost after the drawing. JPG for pages that are mostly photographs, where it makes much smaller files. The JPG version of this page is in the list below.
How many pixels will each image have
The page’s size in inches times the resolution. An A4 page is 1240 × 1754 at 150 dpi and 2480 × 3508 at 300; a US Letter page is 1275 × 1650 and 2550 × 3300. Each row lists the exact size. A page that would pass 16.7 million pixels is drawn smaller, and the note says so.
Can it open a password-protected PDF
No. This page has no way to ask for a password, so a locked file is refused with a message. Open it in a reader, save an unprotected copy, and use that. A file that only restricts printing or copying opens as usual.
Is the PDF uploaded
No. The browser reads the file from your disk and writes the new one on this page. There is no upload endpoint on this site, so there is nowhere for the file to go. Nothing about the document is logged either — this page does not know how many pages your file has.
