What batch conversion changes
One faulty file does not stop the others. You can see which results are in the ZIP and which files are missing.
Pixel dimensions are preserved. Outputs are freshly encoded as sRGB raster files, so embedded EXIF, IPTC, XMP, ICC, and orientation metadata are not retained.
PNG and WebP can keep transparency. JPEG cannot, so any selected source with an alpha channel requires an explicit background choice before the run.
How to batch convert images
- Add your files
Select up to 25 JPEG, PNG, or WebP files. Mixed input formats are fine.
- Pick the output format
Choose one shared output format for the whole batch and adjust quality where offered.
- Convert and download
Convert the batch and download the results together in a ZIP archive or one by one.
Frequently asked questions
How many files can I convert at once?
Up to 25 images per run, and mixed input formats are allowed.
Can I mix JPEG, PNG, and WebP inputs?
Yes. Each file is converted independently to the chosen output format; a file that cannot be converted is reported individually without blocking the rest of the batch.
Are the files uploaded?
No. Conversion runs locally in your browser, and the ZIP archive is generated on your device.
