Hit that "max 200KB" upload limit on the first try — free, no sign-up, processed 100% in your browser.
Why is my PDF so large?
Most oversized PDFs are full of high-resolution images — scans or phone photos saved at print quality. Embedded fonts, duplicated resources and hidden metadata add extra weight on top.
ShrinkPDF downsamples those embedded images to a screen-friendly resolution and re-encodes them, iterating until the file fits your target size. Text and vector graphics are never touched, so documents stay sharp while the images shrink.
Unlike typical online compressors, everything happens locally with JavaScript: your PDF is never uploaded to a server. That makes this the safe choice for contracts, visa documents and anything confidential.
When you need a 200KB PDF
200KB is the classic job-portal limit:
- Job applications — resume/CV uploads capped at 200KB are everywhere; a rejected upload can cost you a deadline.
- School & university admissions — application portals routinely set 200KB per document.
- Bank KYC uploads — identity documents with strict per-file limits.
Set 200KB as the target and download a file that passes validation the first time.
Frequently asked questions
Will my file be uploaded to a server?
No. The entire compression runs in your browser using JavaScript. Your PDF never leaves your device — open DevTools → Network tab while compressing and you will see zero upload requests.
What if my PDF can't be compressed to 200KB?
You will still get the smallest version we could produce, with a clear notice that the target wasn't reached. This usually happens with very dense black-and-white scans or vector-heavy presentations. Splitting the file and compressing the parts separately usually helps.
Does compression affect text sharpness?
No. Compression only re-encodes the embedded images; text and vector graphics are never resampled, so they stay perfectly sharp.
What is the maximum file size?
50 MB per file. Larger files should be split first, then each part compressed.
Does it work on mobile?
Yes — it works in the browsers on iPhone, Android, Windows and Mac. No app to install.
Is there a daily limit? Is it really free?
No limits, no account, no watermark. Free forever for the core compression.
How is this different from iLovePDF or Smallpdf?
Those services upload your file to their servers for processing. ShrinkPDF compresses locally in your browser, so sensitive documents never leave your machine — and you can verify it yourself in the Network tab.
