Re-encodes pages as JPEG for smaller size
Reduce PDF size — privately in your browser
PDFs balloon when they contain scanned images. This tool re-renders each page as a JPEG at a controlled quality level, typically cutting file size by 50–90% while staying readable.
When to use this
- Email attachments that exceed the 25 MB Gmail cap
- Government portals with 2 MB upload limits
- Uploading to job applications, scholarship forms, or loan docs
- WhatsApp Web shares (limited to 100 MB)
How to use this tool
- Choose your PDF.
- Move the quality slider — 70% is a safe default; lower gives smaller files.
- Click Compress & Download.
Frequently asked questions
Will text stay selectable?
No — pages are rasterised to JPEG. Use Compress PDF (lossless) for text-heavy PDFs if you need selectable text; for that keep quality ≥ 85%.
Why is my compressed PDF still large?
PDFs with high-resolution scans are the hardest to shrink. Try quality 50% or target-size tools for strict limits.
Is anything uploaded?
No — everything runs client-side.
