Any format
JPG, PNG, WebP, AVIF — keep original or transcode in the same batch. No separate tool per format.
Compress JPG, PNG, WebP and AVIF locally on your Windows PC. Drop a folder, pick quality 40–95, and shrink images in bulk — no upload, no account, no waiting for a server.
Most image weight is invisible — oversized dimensions, metadata, and quality left at 95. Compressy fixes all three locally.
A familiar Windows workflow — not another upload site.
Choose a folder or individual images. Filter by type, sort by size, search by name.
Pick quality, engine, output format, resize caps. See live estimates per file.
Run locally on 2/4/8 threads. Watch per-file savings and open the folder when done.

You control it. Quality 85 is the default — lower for smaller files, higher for fidelity. Per-file preview shows the trade-off.
Yes. Select a folder, filter by type, and batch on 2/4/8 threads. Originals go to /backup if you overwrite.
