Compress a PDF to 200 KB
For the majority of government and university upload forms worldwide. The compressor searches quality settings until your file fits under 200 KB — and it runs on your own device, so nothing is uploaded.
The compressor is on the front page. Set your target and go — nothing is uploaded.

200 KB is the single most common hard limit on the web, and it is the reason most people go looking for a PDF compressor in the first place. It is generous enough to be achievable for most real documents and tight enough that an unedited phone scan will always blow past it.
The usual culprit is resolution. A phone camera photographs a sheet of A4 at something like 3000×4000 pixels — far more detail than anyone reading the document needs. Bringing that down to roughly 150 DPI keeps every word legible while removing most of the bytes.
How to do it
- Open the compressor on the front page and choose your PDF.
- Leave the method on Target size.
- Type 200 into the target box.
- Press Compress. The tool tries progressively lower resolutions and quality levels, measuring the real output each time.
- Download the result. It is the best-looking version that still fits under 200 KB.
If you cannot get there
When the tool reports a smallest achievable size above your target, it has genuinely exhausted its options. Things that actually help, in rough order of effectiveness:
- Scan in greyscale or black and white. Colour scans carry three channels of data for documents that are almost entirely black text on white paper. This alone often halves the size.
- Crop the margins. Phone photographs of documents usually include a desk, a hand, and a lot of empty space, all of which cost bytes.
- Reduce the page count. Many forms ask for specific pages, not the entire document.
- Rescan at a sensible resolution. 600 DPI is for archival reproduction. 150 DPI is fine for a form upload and a quarter of the size.
Common questions
Can any PDF be compressed to 200 KB?
No. Every document has a floor below which it cannot go while remaining readable. 200 KB is realistic for up to about five text pages, or two to three scanned pages. Beyond that, the honest answer is to reduce the page count or scan in greyscale rather than to compress harder.
Will the text still be selectable?
Not in Target Size mode. Guaranteeing a hard byte ceiling requires rasterising the pages into images, which flattens the text layer. Lossless mode preserves selectable text but cannot promise a specific output size.
Is my document uploaded to a server?
No. Compression runs entirely in your browser. The file never leaves your device, and the tool keeps working if you disconnect from the internet after the page has loaded.
Why does the form still reject my 200 KB file?
Check whether the limit is stated in KB or KiB, and whether the form also restricts page dimensions or requires a specific PDF version. Some portals also reject files whose name contains spaces or non-English characters.
