Features

Use Cases

Email large reports

Many email systems reject attachments over 10–25 MB. Compress a PDF report to fit within the limit before sending.

Upload to web forms

Government, university, and job application portals often impose strict PDF size limits. Compress your file to meet those requirements.

Save storage space

Archive collections of PDFs take up a lot of disk space. Compress each file to free up storage on your device or cloud drive.

Faster sharing and downloads

Smaller PDFs load and download faster, especially for readers on mobile or slow connections.

CMS and website uploads

Content management systems often impose upload size limits. Compress PDFs before uploading to your website or blog.

Frequently Asked Questions

Q: Is my PDF private during compression?

Yes. Compression happens entirely in your browser. Your file is never transmitted to any server.

Q: How much can the tool reduce the file size?

Results vary by content. Image-heavy PDFs often shrink by 40–70%. Text-only PDFs have less room for compression.

Q: Will the text still be readable after compression?

Yes. Text is stored as vector data and is not affected by image compression settings.

Q: What if the compressed file is larger?

This can happen with already-optimized PDFs. In that case, the original quality is maintained.

Q: Can I compress multiple PDFs at once?

Currently one PDF at a time. Repeat the process for additional files.

Q: Is there a file size limit?

No artificial limit is imposed. Very large files (500+ MB) may be slow depending on device performance.
