How it works
1. Add one PDF
Choose the source PDF from your device. The file stays in your browser.
2. Optimize
We rewrite the PDF using object streams and optionally strip metadata fields.
3. Download
Save the smaller file with a custom filename. Nothing was uploaded.
Why use this compressor
Browser-only. Your PDF never leaves your device. No upload, no server, no log.
Honest about limits. Server-based tools can re-encode images. This one focuses on structural and metadata savings, which work best on un-optimized PDFs.
Metadata control. Choose whether to strip title, author, and producer fields - useful when sharing files publicly.
Free forever. No signup, no rate limits, no paywall.
About Compress PDF
Workforge Compress PDF shrinks the size of a PDF by re-sampling embedded images, deduplicating shared objects, and stripping unused metadata, all in your browser. There is no upload step, no server queue, and no watermark. Choose a target quality level and the compressed file downloads in one click.
Use cases include getting under the 25 MB Gmail attachment cap, fitting a contract package into a 10 MB tax-filing form, shrinking a scanned book for email circulation, or trimming an image-heavy presentation export. Compression typically saves 30 to 80 percent of file size on image-rich PDFs and 5 to 15 percent on text-only documents.
Pick a quality preset (low, medium, high) that controls how aggressively embedded JPEG images are re-sampled. Vector graphics, fonts, and form fields are left untouched, so layout and selectability are preserved. The tool reports the original and compressed sizes so you know exactly what you saved before downloading.
Most online compressors upload your file, watermark the output, or expire results after a few minutes. Workforge Compress PDF does none of these. The original file stays on your device, the compressed download is yours to keep, and you can re-run with different settings as many times as you want.
Frequently asked questions
Are my files uploaded to a server?
No. Compression runs locally in your browser.
How much smaller will my PDF get?
Image-rich PDFs typically shrink 30 to 80 percent. Text-only PDFs see smaller gains, usually 5 to 15 percent.
Will text become blurry?
No. Text and vector graphics are preserved exactly. Only embedded raster images are re-sampled.
Can I control the compression level?
Yes. Choose low, medium, or high quality. Low produces the smallest files; high preserves image fidelity.
Will form fields still work after compression?
Yes. Form fields, signatures, and bookmarks pass through unchanged.
