Details and tips
How it works
The browser detects each image’s real format, decodes it with orientation correction and encodes all outputs in the chosen format. Pixel dimensions remain unchanged. JPG fills transparent areas with the selected color; PNG and WebP can retain transparency.
Made for everyday images
Convert a mixed image collection for a content system, prepare WebP web assets or provide JPEG files to a workflow that requires them.
Frequently asked questions
Can I upload a ZIP of images?
Yes. Standard unencrypted ZIP files can contain JPG, PNG and WebP images in subfolders. Other files, hidden files and nested archives are skipped. RAR, 7z, ZIP64 and split archives are not supported. Files stay on your device.
What are the batch limits?
Up to 100 images and 250 MB of images after extraction per batch. Each ZIP is limited to 250 MB and 1,000 entries. Each input and output image must fit within 8,192 pixels per side and 16 megapixels; completed results are capped at 250 MB.
What happens if a file fails or names repeat?
Each image has its own status. Failures do not stop the remaining images. Download completed files individually or in a ZIP; output folders are flattened and duplicate names receive a numeric suffix. Cancel keeps completed results.
Can one batch contain different image formats?
Yes. JPG, JPEG, PNG and WebP can be mixed, including inside ZIP subfolders. All successful outputs use the chosen format.
What happens to transparent pixels?
PNG and WebP preserve transparency. JPEG fills transparent areas with the selected background color.
