Up to 20 images, 25 MB and 16 megapixels each; 40 MB combined and 24 megapixels total. Decoded sequentially. PNG results in a ZIP; smaller dimensions do not guarantee smaller files.
Animated files are processed as a still image. Re-encoding may change color profiles and metadata.
Instructions and examples
From input to output
- Add images to the queue and arrange them in the desired order.
- Enter Width px and select Resize batch.
- Read the per-file dimensions, download the ZIP and inspect the extracted PNG files.
Settings and result behavior
- One width from 1 to 4,000 pixels applies to every source. Each height is calculated from its original proportions.
- Exports are PNG, named with a sequence number and a cleaned source filename. There is no format or quality selector here.
A worked example
- Input
Two images: 1600 × 900 and 1200 × 1200.
- Settings
- Width px: 800.
- Expected result
A ZIP containing an 800 × 450 PNG and an 800 × 800 PNG.
Supported input and limits
Choose PNG, JPEG, WebP, GIF or BMP that your browser can decode. Animated sources are processed as a still image. Re-encoding can change metadata and color rendering. PNG exports are packaged together in a ZIP, with a 40 MB batch output cap.
Up to 20 images, 25 MB and 16 megapixels each; 40 MB combined and 24 megapixels total. Decoded sequentially. PNG results in a ZIP; smaller dimensions do not guarantee smaller files.
If the result is unexpected
- If the ZIP exceeds the limit, use a smaller width or fewer sources.
- A width above the original upscales it and may look soft. Use Resize images if you need other formats or fit controls.
Check before using the result
Extract the archive and check every image’s dimensions and legibility. Smaller pixel dimensions do not guarantee smaller encoded files.
