Just drop your PDF — we automatically analyze it and pick the best compression settings to shrink the file without hurting quality.
No sign-up required · Compression level is chosen automatically
We scan a sample of your PDF's pages to measure their resolution and visual complexity,
then pick the lightest compression that keeps everything sharp.
Text-heavy pages get compressed gently. Image-heavy or already-large pages
get compressed more aggressively.
Everything happens locally in your browser — nothing is uploaded.
