Things to Know
Compression removes internal bloat but does not downscale images or reduce image quality. If your PDF contains many high-resolution images, the size reduction may be modest.
Frequently Asked Questions
How much smaller will my PDF get?
Results vary. Documents with lots of unused objects or redundant data can shrink 30-70%. Image-heavy PDFs may see more modest reductions since images are not re-compressed.
Does compression affect quality?
No. The compressor removes unused internal objects and optimizes streams without altering any visible content, images, or text.
Why is my PDF so large in the first place?
Common causes include embedded fonts that aren't used, high-resolution images, redundant metadata, and leftover editing data from the PDF creation tool.
Can I compress multiple PDFs at once?
Currently the tool processes one PDF at a time. For batch compression, run each file through individually.
Is there a file size limit?
The tool handles files up to 100MB in your browser. Very large files may take longer depending on your device's memory.
