About this app
Squish is a no-nonsense bulk compressor for the image formats your workflow actually ships — PNG, JPEG, WebP, and AVIF. Drop in hundreds of files, choose a quality level, pick whether to overwrite or write alongside the originals, and Squish re-encodes the lot in parallel. Every row in the table reports the before and after byte counts, so you see exactly what shrank. The footer sums the whole batch: X megabytes saved, Y percent smaller. No accounts, no uploads, no re-encoding artifacts from third-party CDNs.
Key features
- Bulk compression for PNG, JPEG, WebP, and AVIF
- Single quality slider for the whole batch (30–100)
- Keep original format or convert to a smaller one in the same run
- Save alongside originals, overwrite, or write to a chosen folder
- Per-file size before/after with saved-bytes delta
- Footer total shows cumulative savings across the batch
- Fully offline — no uploads, no re-encoding through third parties
Ratings & reviews
Squish is exactly what I was looking for. Lightweight, fast, and does the job without unnecessary bloat. Highly recommend.
Been using Squish daily for a few weeks now. The interface is clean and intuitive. Great addition to the BundlApps catalog.
Switched to Squish from a paid alternative and honestly prefer it. Runs locally, no account needed, just works.
