Your compressed file is ready with the before/after size shown.
What gets compressed
Three file types, one tool
Image compression
50–65% smallerJPEG, PNG, WebP compressed using Pillow. JPEG quality 75 — visually indistinguishable from the original at ~10ms processing time. PNG uses lossless deflate (no quality loss).
PDF compression
20–80% smallerPyMuPDF stream compression + Pillow image downsampling. Text PDFs shrink 20–30%. Image-heavy or scanned PDFs shrink 50–80% because embedded images are downsampled and recompressed.
Video compression
60–72% smallerFFmpeg with H.264 CRF 28 — significant size reduction while keeping the video watchable. Supports MP4, MOV, AVI, MKV.

Can I compress images online for free?+
Yes — FixTheFile compresses JPEG, PNG, and WebP images online for free using Pillow. JPEG at quality 75 typically shrinks images 50–65% with barely perceptible visual difference. PNG uses lossless compression so quality is exactly preserved. No signup needed for your first compression.
How much does PDF compression reduce file size?+
It depends on what's inside the PDF. Text-heavy PDFs typically shrink 20–30% from stream compression. Image-heavy PDFs (scanned pages, photos) can shrink 50–80% because FixTheFile extracts each embedded image, downsamples it to a maximum 1600px dimension, recompresses it as JPEG quality 72, and re-embeds it. This is the technique that actually makes a difference for large PDFs.
Is there a video length limit for compression?+
Yes — videos must be under 90 seconds and under 150MB. This limit exists because video compression with H.264 is compute-intensive: a 60-second 1080p video takes about 2 minutes to process on our server, and the server has a 300-second request timeout. Videos longer than 90 seconds risk hitting that limit. Trim your video first, then compress it here.
Will my image look different after compression?+
At JPEG quality 75, the visual difference is barely perceptible for photos. Most users cannot tell a quality-75 JPEG from the original at typical viewing sizes. PNG files use lossless compression (compress_level=9) so they look exactly identical to the original — only the file size changes.
What formats are supported for compression?+
Images: JPEG, PNG, WebP. PDFs: any PDF up to 500MB. Video: MP4, MOV, AVI, MKV — under 90 seconds and 150MB. GIF is processed but results vary. ZIP, RAR, and audio files are not supported for compression.
