JPG & PNG image compressor
Reduce JPG and PNG dimensions or export JPEG at lower quality, compare file sizes, and download a local batch.
How to use this tool
- Select a small batch and choose JPEG for smaller photographic images or PNG for transparency.
- Set maximum width and JPEG quality. Images are never enlarged.
- Inspect the preview and byte comparison before downloading.
Keep the original files and inspect the exported result before publishing or sharing it. Processing happens on this device; engine and library assets download when needed.
Frequently asked questions
Will PNG always become smaller?
No. PNG has no lossy quality setting here. Reduce dimensions or choose JPEG for photographs. Re-encoding can produce a larger file, which is clearly reported.
Are original files replaced?
No. Every download is a new file. Re-run with different settings to compare results.
