Image Compressor
What it does
Re-encodes images locally to shrink their file size, two ways: a fixed quality slider, or a size budget — give it a KB target per image and it binary-searches the quality until the output fits. An optional max-dimension resize handles oversized photos in the same pass. JPEG and WebP sources keep their format; PNG sources re-encode as WebP (the lossy pipeline that makes compression possible). Batch supported, with a total-saved summary.
Your images never leave the page — that is the difference from online compressors, which upload every file you give them.
How to use
- Drop one or more images.
- Choose the mode: fixed quality, or a target size in KB.
- Optionally cap the longest dimension (0 keeps the original size).
- Press Compress, review the per-image savings, and save.
Examples
A 4.1 MB phone photo compressed at quality 75 typically lands near 600–900 KB (−80% or so); the summary line reports the exact total.
Target mode on the same photo with a 200 KB budget finds the highest quality that fits — usually around q55–q65 — and reports the quality it chose.
Good to know
- Already-optimized files (small WebPs) may grow slightly; the delta turns red to tell you before you save.
- PNG sources become WebP because PNG’s lossless pipeline cannot hit aggressive size targets.
- The max-dimension resize is part of the same re-encode — no double compression pass.
