How Does PDF Compression Work?

We don't just delete pages. We optimize the internal structure of the file to save space without ruining readability.

Image Optimization

PDFs are often huge because they contain high-resolution images. We downsample them (e.g., from 300 DPI to 144 DPI) which saves massive space while looking identical on screens.

Font Stripping

Many PDFs embrace entire font families even if they only use a few letters. We remove unused subsets to shave off valuable kilobytes.

Structure Cleanup

We remove hidden metadata, redundant objects, and bookmarks that bloat the file size without adding value to the reader.

Who Uses This PDF Compressor?

  • Job Seekers: Creating a portfolio or resume under 2MB for job portals is a struggle. We make it easy, ensuring your application gets through.
  • Freelancers & Businesses: Gmail has a 25MB attachment limit. If your invoice or contract is too big, compress it here to send it in a single email.
  • Students: Blackboard, Canvas, and other university portals often have strict upload limits for assignments. Shrink your scanned PDFs to fit the requirements.
  • Government & Legal: Uploading tax documents (e.g., GST portal, IRS) often requires small file sizes. Use our secure tool to comply without risking data privacy.

Frequently Asked Questions

Q: Will my text become blurry?

No. Text in PDFs is typically vector-based, meaning it stays sharp at any size. We primarily optimize images. Your contracts and reports will remain perfectly readable.

Q: Is my document stored?

No. We reiterate our privacy guarantee: We use client-side WebAssembly technology. Your sensitive PDFs remain on your device and are never uploaded to our cloud.

Q: Can I compress a 200MB file?

Yes. Because we use your computer's CPU and not our server limits, you can process very large files as long as your device has enough memory.

Q: How much space will I save?

It depends on the file. Scanned documents and image-heavy reports can often be reduced by 30% to 70%. Text-only files may see smaller reductions.
