Batch image compressor
Resize and convert JPG, PNG and WebP images on your device. Download individually or as a ZIP.
Choose images to begin.
Smaller files, predictable dimensions
Choose up to 20 JPG, PNG or WebP files. Set the longest edge and an output format, then process the batch. Each image keeps its aspect ratio and is never enlarged.
Worked example
For a 4000 × 3000 image with a longest edge of 1600, the result is 1600 × 1200. File size depends on image detail, format and quality; a smaller output is not guaranteed.
Limits worth knowing
JPEG is suitable for photos and uses a white background for transparent pixels. PNG retains transparency and ignores the quality slider. WebP supports transparency but export support varies by browser. This tool uses your browser’s encoder and can remove metadata; it does not preserve animation. It handles still JPG, PNG and WebP files only. Limits: 20 MB per file, 100 MB per batch, 25 megapixels per image and a 4096-pixel output edge. Browser decoding may still use substantial memory.
Does this upload my images?
No. Image conversion runs on your device. The hosting provider receives page requests, but the application does not upload your selected images.
