1MB compress

Free file compression. No uploads, no accounts, no limits.

1MB Compress is a free, browser-based file compression and optimization platform that lets you compress images, videos, GIFs, and PDFs — or merge multiple PDFs — without uploading anything to a server. All processing happens locally in your browser using WebAssembly and native browser APIs, meaning your files never leave your device. Core Features: - Image Compression — Reduce JPEG, PNG, WebP, GIF, BMP files to target sizes like 5MB, 2MB, 1MB, or smaller using smart quality reduction and optional resolution scaling - Video Compression — Compress MP4, WebM, MOV, AVI videos to target sizes using FFmpeg WebAssembly, processing entirely in-browser - PDF Compression — Reduce PDF file sizes through lossless optimization (stripping metadata, compressing internal structure) or by rasterizing pages at high resolution - PDF Merging — Combine multiple PDFs locally in any order, then optionally compress the merged result - GIF Optimization — Reduce animated GIF sizes by optimizing colors, frame rate, and resolution - PDF Password Protection — Add or remove password protection from PDFs, all processed locally - Batch Processing — Handle up to 20 files at once Key Differentiators: - 100% Private — Nothing is ever uploaded; files are processed entirely on the client - No Sign-up — No accounts, no limits, no credit card required - Instant Processing — Full CPU speed with no server queue waiting - Cross-Format — Images, videos, GIFs, PDFs, and merge workflows in one place - Niche Use Case — Specifically targets embassy/passport document requirements (e.g., Indian embassies requiring documents under 1MB)
