Compress PDF to 1 MB
Compress a PDF toward 1 MB for a portal, form upload, or size cap. This opens the free on-device compressor with a 1 MB target. Exact size depends on the file; already-optimized or image-heavy PDFs may not reach 1.00 MB.

FAQ
- Will my PDF always be exactly 1 MB?
- No — exact size depends on the PDF content. We aim for approximately 1 MB; already-optimized files may not shrink as much, and heavy scans may need stronger compression or fewer pages.
- Is my file uploaded?
- No. Compression runs in your browser on your device.
- How is this different from Compress PDF?
- This page is for a 1 MB size goal and opens the compressor with that target. The general Compress PDF tool also supports Low/Medium/High levels and other size targets (about 500 KB–5 MB). For limits and feasibility, read the under-1 MB guide.
- Are there file limits?
- Validated PDFs are limited to about 100 MB and 250 pages. Within those bounds, very large files may also be limited by your device memory.
