Bulk Image Compressor
The single-image compressor, scaled up: drop a whole shoot or a folder of product photos and compress them all with one settings block. Choose quality mode for everyday shrinking, or exact-size mode to bring every file to the same target (200KB for a portal upload, 500KB for email) — files that genuinely cannot reach the target are delivered at the smallest size found and named "-smallest-possible", so the report is honest per file.
Processing runs two files at a time with per-file progress, pause/resume, cancel and retry, and everything downloads as one ZIP.
Drop images to compress in bulk

Frequently asked questions
What does "-smallest-possible" in a file name mean?
In exact-size mode, that file could not reach your target even at the lowest quality and smallest dimensions the algorithm allows (usually a very noisy photo or a tiny target). You still get the smallest version found — the name just refuses to pretend it hit the target.
How many images can I compress at once?
There is no fixed count limit; the queue processes two at a time so your browser stays responsive. Very large batches on low-memory devices may be slower — split them if the tab struggles.
Does bulk compression remove metadata?
Yes — every file is re-encoded, which strips EXIF and GPS metadata. Use the Metadata Viewer first if you need to record anything from it.
