Why PDFs Get So Large
Most oversized PDFs aren't bloated by text — text is tiny. The weight almost always comes from embedded images: a page scanned at 600 DPI can be 5-10x larger than it needs to be for on-screen reading, and each embedded font, thumbnail preview, and bit of leftover editing metadata adds more on top. Compression works by re-encoding those images at a lower (but still readable) resolution and stripping the redundant data, without touching the actual text.
Common Situations
A scanned contract or ID document that's too big for an email attachment limit (typically 20-25MB), a photo-heavy report that's slow to upload to a job portal or government website, or a batch of scanned pages you want to archive without eating your cloud storage quota.
How to Use
1. Upload your PDF.
2. Click Compress PDF — no settings to configure, it automatically balances size against readability.
3. Download the smaller file and compare it against the original if you want to check quality.
Frequently Asked Questions
Will compression make my PDF blurry?
Text stays sharp either way since it isn't rasterized. Embedded photos and scans are recompressed, so very close zooming may show more compression artifacts than the original — but for normal reading and printing the difference is usually not noticeable.
How much smaller will my file get?
It depends entirely on what's inside — a text-only PDF may barely shrink since there's nothing to compress, while an image-heavy scan can often drop by 50-90%.
Is there a file size limit?
Very large files (several hundred MB) may take longer or fail depending on your connection — if you hit issues, try splitting the file first and compressing the pieces separately.
