Free Online Image Optimizer What it's for

Turn a PDF into images

Drop in a PDF and take back one image per page, already compressed. Useful when something will accept a picture but not a document — an upload form, a listing, a message — and for pulling a single page out of a report without sending the whole thing.

Questions

Why would I want images instead of the PDF?

Because plenty of things take a picture and refuse a document. Marketplace listings, older upload forms, messaging apps, and the image field on a web page all want a JPEG. Pulling out page four as a picture is also a good deal less than sending somebody a fourteen-page report.

Will the text still be readable?

Yes for anything meant to be read on screen. Pages are rendered at 150 dpi, which keeps ordinary body text comfortable — a page of a contract comes back around 200 KB. It is not the resolution you would choose for print or for running text recognition over afterwards.

Can it go the other way — images into a PDF?

Not for pages that came out of a PDF, and the reason is worth stating. They would go back in as pictures: a text PDF stores glyph references, a rasterized one stores pixels. A 205 KB thirteen-page report came back at 1.72 MB — eight and a half times the size — so the button is not offered here, because it would be bad advice with a button on it. If you upload photographs or scans instead, the results table does offer “Download as one PDF”, assembled in your browser so nothing is uploaded twice. Either way the pages are pictures, so their text cannot be selected or searched.

Can it make my PDF smaller and still a PDF?

No. That is a genuinely different job — it means taking the document apart, recompressing what is inside it, and putting it back together, and this does not do that. What you get here is images.

Why the 50-page limit?

Two reasons, and the honest one is capacity. Rendering a page takes about forty milliseconds, so fifty pages are rendered in around two seconds — but then every page has to be stored where your browser can fetch it, and that is the larger half by a long way: a 30-page document measured about 10 seconds end to end on an idle server, and longer when other documents are being rendered at the same time. Fifty is where one document stops crowding out everybody else's. Longer documents work in batches of fifty, and the settings stay put between them.

What happens to my document?

It is rendered, the pages are stored at a random unguessable address, and everything is deleted automatically. The PDF itself is discarded as soon as the pages are made — it is never stored. Nothing reads the contents.
