The usual ceiling for e-mail attachments on older corporate systems, and for a good number of tender and compliance portals. This page opens the target-size compressor with the ceiling already set to 500 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. Comfortable. Five to eight scanned pages come out clean, and the quality loss is not something you would notice without the original beside it.
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 500kb, reduce pdf size to 500kb, pdf size reducer 500kb, make pdf less than 500 KB. It is the same tool whichever way you found it.
For most documents, yes. There is enough room for the ladder to stop at a high resolution, so the result is close to the original to look at. The words are still part of the image afterwards — that is true at every ceiling — but the picture of them is a good one.
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. A document that misses 500 KB is normally a long photographic scan; splitting it in half usually gets both parts well under.
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.
