A better way to convert image batches
Add images your way
Drop a mixed selection, choose multiple files, or choose an entire folder where your browser supports it.
Set once, convert all
Choose quality, resize, and output mode once, then let the queue process every image in order.
Download with confidence
Compare the original and converted size, save one file, or download the full batch as a ZIP.
Conversion queue
Review every image before you save it
Every selected file receives a thumbnail, filename, original size, and status. Remove anything that does not belong in the batch. Previews use lazy browser loading to help the page stay responsive with a larger collection.

Bulk WebP conversion without the repetitive work
WebP is a modern image format that can preserve a photo or graphic at a smaller file size than traditional formats. That makes it especially useful for websites, product galleries, support documents, and shared folders. Instead of exporting images one at a time, this tool lets you make consistent WebP copies from a complete group of files.
Choose the source images, review the queue, and apply a single set of settings to the batch. The completed cards show both the original and converted file sizes so you can see what your choices achieved before you share or publish the results.
Why convert several images to WebP?
Small savings across a collection of images can add up to faster uploads, lighter pages, and easier file sharing. A batch process also gives every item a consistent quality and maximum width.
- Prepare a collection of website images for faster delivery.
- Standardise mixed JPG and PNG folders.
- Make a large group of images easier to email or upload.
- Create WebP copies while leaving originals untouched.

When should you use it?
Use a bulk WebP converter when you are preparing a website collection, product images, documentation, or a shared project folder. It is ideal when your whole set needs consistent settings.
Always keep your source images. WebP is an export format, not a replacement for the original master files you may want to edit later.
Best practices and common mistakes
Start with original files
Repeatedly converting a compressed JPG can exaggerate artifacts. Use the best source you have.
Test a few representative images
Try a photo, a graphic, and an image with text before sending a very large batch.
Do not over-compress
Very low quality can make soft text and visible blocks. Inspect results at normal viewing size.
Privacy and security
This page uses client-side browser processing whenever possible, so images do not need a server conversion upload. The active queue remains in the page and can be cleared with Remove all.
For sensitive images, work from a trusted device and always verify the files you are downloading and sharing.
Performance
Images use memory while they are decoded and rendered. The converter processes the queue one file at a time to make larger batches more manageable. For very large source files, test a small group first and resize only where it helps.
Supported formats
Also try Image Compressor, Resize Image, JPG to PNG, and PDF to JPG.
