About this tool & FAQ

Bulk Image Converter

Convert up to 50 images to JPG, PNG, or WebP in one pass, then download the results together as a ZIP.

Bulk Image Converter changes a mixed batch of up to 50 images to one common format without making you repeat the same steps file by file. Add JPG, PNG, WebP, AVIF, HEIC, HEIF, or GIF images together, choose JPG, PNG, or WebP as the output, and press Apply when the batch is ready. Conversion and ZIP creation happen locally in your browser, so the images never need to leave your device.

How it works

1. Add up to 50 images

Choose several images at once or drag them onto the tool. You can mix JPG, PNG, WebP, AVIF, HEIC, HEIF, and GIF files in the same batch, then select or remove individual images before conversion begins.

2. Choose one output format

Pick JPG, PNG, or WebP for the whole batch. JPG is widely compatible but fills transparent areas with white; PNG keeps transparency with lossless output; WebP usually balances quality and smaller file sizes. Nothing is processed until you press Apply.

3. Apply and download one ZIP

The browser converts each image independently and shows a thumbnail for every result. Download the complete batch as one ZIP containing distinct filenames with the output extension you selected.

Frequently asked questions

How many images can I convert at once?
You can convert up to 50 images in one batch. The limit keeps local memory use predictable on phones and laptops.
Can a batch contain different input formats?
Yes. One batch can mix JPG, PNG, WebP, AVIF, HEIC, HEIF, and GIF inputs, and every image is converted to the one output format you choose.
What happens to transparency when converting to JPG?
JPG cannot store transparency, so transparent and semi-transparent areas are placed on a white background. Choose PNG or WebP when transparency needs to remain.
Are my images uploaded?
No. Image decoding, conversion, previews, and ZIP creation all happen in your browser on your device.
