Shrink PDF file size in your browser. Private by default — your document never leaves your device.
Drag and drop a PDF here, or choose a file to compress in your browser.
Processed in your browser. Nothing is uploaded to a server.
Compress PDF files free in your browser with SnapBit’s private PDF Compressor. Shrink image-heavy documents, scans, and exports without uploading to a server — choose quality and DPI, then download a smaller PDF in seconds. Large PDFs clog email inboxes, slow downloads, and hit upload limits on forms and CRMs. Most online compressors require uploading sensitive documents to remote servers. SnapBit processes pages locally: each page is rendered at your chosen resolution, re-encoded as JPEG, and rebuilt into a new PDF. You stay in control of the size/quality tradeoff with Strong, Balanced, and High quality presets. This client-side approach is ideal for privacy-sensitive files — contracts, IDs, medical scans, and internal reports — while still delivering meaningful size reductions for photograph- and scan-heavy PDFs. If a file is already optimized, the tool keeps the original instead of giving you a larger download. Use it alongside Image to PDF and Image Compressor when building document workflows entirely on-device. Enhanced server compression (optional, consent-based) is planned for cases that need Distiller-level optimization while keeping private mode as the default.
It renders each page in your browser, re-encodes pages as JPEG at your chosen quality and DPI, then rebuilds a smaller PDF — all on your device. No file is uploaded to a server.
Not in the current private (client-side) mode. Pages are rasterized for maximum size reduction. A future optional server mode may preserve text when you consent to upload.
No. Private mode processes the PDF entirely in your browser. Nothing is sent to SnapBit servers.
Some PDFs are already optimized. If the compressed output is larger than the original, SnapBit keeps the original and tells you it was already optimized. Try a stronger preset (lower DPI / quality) for image-heavy files.
Balanced (≈100 DPI, ~72% quality) works for most documents. Use Strong for email attachments and High quality when you need sharper screenshots or detailed scans.
Your data never leaves your browser. All processing is done locally on your machine, ensuring maximum security and speed. No server calls, no tracking, no risk.
