Compress PDF to 200KB
You can get a PDF under 200KB without uploading it anywhere. The first attempt is lossless -- the file is rewritten with object streams and duplicate resources dropped -- and if that measures under 200KB you keep selectable text, working search and crisp glyphs at any zoom. Only if lossless is not enough do the pages get rasterised, and you are told before that happens rather than after.
2Add your file
Video, images and PDFs, all compressed on your own machine. No upload, no account, no watermark, no limit on how many files.
The same tool takes video, images and PDFs, at this size or any other.
Mechanism
How this works
Four steps. The byte count is measured at every one of them.
- 01
The document is opened locally
Page count and size are read in your browser. A PDF is often the most sensitive thing anyone compresses, and this one does not leave the machine it is on.
- 02
Lossless is tried first, and measured
The file is rewritten with object streams and duplicated resources dropped. If that alone measures under 200KB, it is what you get -- text still selectable, search still working, glyphs still sharp.
- 03
Only then are the pages rasterised
If lossless was not enough, each page is rendered to an image. That reaches any target, but it is permanent: Ctrl+F finds nothing afterwards. You are told before it happens, not after.
- 04
Render scale is bisected, not guessed
Scale is searched before JPEG quality, because too few pixels reads as a small scan while heavy JPEG on text edges reads as something being broken. The best result measured under 200KB ships.
Questions
Compressing PDF to 200KB
- How do I compress a PDF to 200KB?
- Drop the file into the tool on this page -- the target is already set to 200KB. The work happens in your browser on your own machine, so there is no upload, no queue and no account. The output is measured before you are given it, so it is genuinely under 200KB.
- Is that exactly 200KB, or approximately 200KB?
- Under it, and verified. The byte count of the finished file is measured and compared against the limit before anything is handed back, and if it came in over, it is done again. 200KB here means 200 decimal kilobytes -- 200,000 bytes -- which is the smaller of the two readings a platform might intend, so it clears either.
- Will the text still be selectable after compressing to 200KB?
- If the lossless pass reaches 200KB, yes -- the text, the search index and the accessibility tree are all untouched. If it does not, reaching 200KB requires rendering the pages to images, which ends selectable text permanently. You are told which of the two happened, and warned before anything is rasterised rather than after.
- Is it safe to compress a confidential document here?
- The file is never uploaded. There is no server to send it to -- the whole pipeline is JavaScript running in your own browser tab, which is why there is no queue and no account. Nothing about the document reaches us, including its name.

- Compressing a scanned PDFA scan has no text to protect, so the usual lossless pass saves almost nothing. What is left is a resolution decision — and there is a right way to make it.
- Compressing a PDF for an online formPortals demand documents under 100KB, 200KB or 500KB and reject anything over without saying by how much. Here is how to hit the number and keep it readable.
- Compressing a PDF without losing its textMost PDF compressors flatten your pages into images, which silently ends search, copy-paste and screen reader access. A lossless pass should come first.
