A ceiling that turns up on job applications and bank forms, and one of the more forgiving ones. This page opens the target-size compressor with the ceiling already set to 300 KB, so the only thing left to do is drop the file in. The tool works down a ladder of resolutions and JPEG qualities rather than guessing once, and stops at the best quality that still fits. Three or four scanned pages hold up well, and a colour scan often keeps its colour rather than being flattened to greyscale to make the number.
This runs in your browser. The file is not uploaded, there is no account to create, and nothing is added to the document you download.
Also searched for: compress pdf to 300kb, reduce pdf size to 300kb, pdf size reducer 300kb, make pdf less than 300 KB. It is the same tool whichever way you found it.
Usually. Colour is only dropped when the ladder runs out of room, and at 300 KB there is normally enough headroom for a few pages to keep it. A long or very detailed scan may still be converted to greyscale, and the page says so when it happens.
Then you are told so rather than handed a file that misses the mark quietly. The smallest readable version is offered instead, with its actual size, and you are never given something larger than what you put in. Check whether the file is a scan at 600 DPI — those start enormous, and the first attempt already gives back most of the weight.
Yes. Nothing is re-rendered: the words, the fonts and the vector artwork are carried across untouched and only the images inside the file are re-encoded, so Ctrl-F and copy-paste keep working on the compressed copy. That is also why a PDF which is already only text may not reach the ceiling — there is nothing heavy in it to give up.
It is handed straight back, untouched. The ceiling is the whole requirement and it is already met, so re-rendering it would only make a smaller file worse — and in some cases larger.
No. The file is opened, changed and written by this browser tab — it is never sent to a server, so there is no queue to wait in and nothing to delete afterwards. Once the page has loaded you can turn the network off and the tool still works.
