Batch Image Resizer
Resize JPG, PNG, AVIF and WebP images by percentage and reduce their file size, directly in your browser.
Quality applies to JPG and WebP. PNG uses lossless encoding.
Drop JPG, PNG, AVIF or WebP images here
Choose settings before adding images; changes apply to new files only. Dimensions keep their proportions, rounded to whole pixels. AVIF input requires browser support. Output is WebP, JPG or PNG. JPG uses a white background for transparency. Animated images become a single static frame.
Images stay in your browser and are never uploaded. Smaller dimensions do not always mean smaller files; compare the results or lower quality.
