Batch Image Resizer
Resize all your images at once by width, height, percentage or exact size, or compress them under a maximum weight (e.g. 200 KB), as JPG, WebP or PNG.
In weight mode, quality is lowered first (down to 35%), then the image is scaled down if needed. PNG has no quality setting: only its size is reduced.

About this tool
The batch image resizer processes all your images at once: fit within a box (for example 1920 × 1080), fixed width or height, percentage, or exact size with centre crop or bars. Handy to prepare photos for a website, an online shop, an email or a form that limits file size.
Maximum weight mode compresses each image under the limit you set, for example 200 KB: quality is lowered first, then the image is scaled down if needed. Choose the output format (same, JPG, WebP or PNG), quality and a name suffix with the dimensions, then download the images one by one or as a ZIP.

Frequently asked questions
How do I get images under 200 KB?
Choose “Maximum weight” mode and enter 200. Each image is compressed, then scaled down if needed, until it is under the limit.
Why does my PNG get heavier?
PNG is lossless: re-encoded, it can grow. For photos, prefer JPG or WebP.
Are photos enlarged?
No, unless you tick “Allow enlarging”. Percentage and exact size modes always apply the requested size.
Are my images uploaded?
No, all processing happens in your browser.
