This tool processes files locally in your browser using the File API. Select or drag a file below to get started.
Batch mode. Select multiple images and this tool will process them one by one in your browser with progress updates.
Batch Image Converter runs locally in this browser. Large files may take longer depending on your device memory and browser limits.
Direct Answer
Use the Batch Image Converter when a site requires a different image format or you need several files changed to JPG, PNG, or WebP. The conversion runs locally in your browser.
When to Batch Convert a Whole Folder of Images
Converting one file at a time makes sense for a single photo, but a website migration, a mismatched folder of downloads, or a bulk upload requirement calls for converting many files in one pass.
- Convert a folder of mixed formats to one consistent target format, such as everything to WebP for a faster website.
- Fix a batch of files saved in the wrong format for an upload portal that only accepts JPG or PNG.
- Clean up a download folder that has an inconsistent mix of image formats before archiving or sharing it.
What Happens Per File in a Mixed Batch
Batch conversion applies one target format to every file, but the effect on each individual image still depends on what that file started as.
- Every transparent PNG in the batch loses transparency the same way when converting to JPG, since JPG has no alpha channel.
- Animated files in the batch, like animated WebP or GIF, flatten to a single still frame if the target format is a static one.
- Converting to a lossy format applies compression to each file individually, so results vary by each image's own content.
Resize, Crop, or Compress?
Most image upload problems fall into one of three jobs. Choose the tool based on the rule shown by the website or app.
- Use Image Resizer when the requirement mentions width, height, pixels, dimensions, or scale.
- Use Image Cropper when the subject needs better framing, a square crop, or background edges removed.
- Use Compress Image to 2MB, Compress Image to 1MB, or Compress Image to 500KB when the requirement mentions KB, MB, file size, or maximum upload size.
Privacy-First Browser Processing
Many utility sites ask you to upload files, drafts, images, or spreadsheet exports to a remote processing server. Tools Village is built around browser-side workflows where supported, so the page can process the selected file or pasted text locally in your current browser session instead of requiring an app-backend upload.
- Useful for sensitive work such as customer CSV exports, unreleased page metadata, private photos, internal reports, and document cleanup.
- No signup is required, so you can complete the task without creating another account or project workspace.
- For very large files, practical limits still depend on your browser, device memory, and the APIs available on your device.

Frequently Asked Questions
Can I put both JPG and PNG files in the same batch and convert them all to one format?
Yes. Batch conversion typically accepts mixed source formats and applies the same target format, such as JPG, PNG, or WebP, to every file, regardless of what format each one started as.
What happens to transparent PNGs when I batch convert everything to JPG?
Every transparent PNG in the batch loses its transparency the same way, since JPG has no alpha channel. Each file's transparent areas get filled with a background color individually, so check PNGs with important transparency before batch-converting the whole set to JPG.
Will batch converting change the quality of my images?
Converting to a lossy format like JPG applies compression to each file, which can introduce a small amount of quality loss, while converting to a lossless format like PNG preserves detail but often increases file size. Converting to WebP can go either way depending on the mode used.
Why would I batch convert a whole folder of images to WebP?
A common reason is preparing a website's image library for faster loading, since WebP files are often notably smaller than the same images saved as JPG or PNG, without a big visible quality difference for most photos.
Do all the output files keep their original file names?
Typically yes, aside from the file extension changing to match the new format, for example photo.png becoming photo.jpg, so you can still match each converted file back to its source.
Can I batch convert images to different formats within the same run, like some to JPG and others to PNG?
Not usually in a single pass. One target format applies to the entire batch; run separate batch conversions if different files need to end up as different formats.
Will batch converting resize my images too?
No. Format conversion changes the file type and compression method, not the pixel dimensions, unless you also use resizing settings or a separate resize step alongside the conversion.
What happens if a file in my batch is already in the target format?
It is usually processed and re-saved in that same format again, which can slightly change its compression, or skipped, depending on the tool. Either way it won't cause an error, since converting a file to the format it's already in is a low-risk case.
