Bring image-heavy PDFs under 2MB without visible quality loss — free, no sign-up, 100% in-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 2MB PDF
2MB fits the documents that are big for a reason:
- Immigration & visa portals — strict about file size, and these documents are sensitive: never uploading them matters.
- Design portfolios — multi-page, photo-rich PDFs that must stay under mail server limits.
- Academic reports — long documents with figures and scanned pages.
At 2MB you are rarely trading readability for compliance — just trimming a file that was needlessly large.
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 2MB?
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.
