About Image resizer conversion
Phones capture photos at 12 to 50 megapixels, which is far more than you need for an email, a classified ad, a résumé portal, or a blog post. Many upload forms reject anything above a few megabytes. Resizing to a sensible maximum such as 1920 pixels wide is the most effective way to cut file size, and it often matters more than which format you choose.
The Matching Sox resizer works with bounding limits. You type a max width, a max height, or both, and every image is scaled proportionally so it fits inside that box — the aspect ratio is always preserved, so nothing gets stretched or squashed. Images already smaller than your limits are left at their original size; the tool never enlarges, which would only add blur.
Because resizing happens during conversion, you also choose the output format and quality at the same time: JPEG for photos, PNG for graphics needing lossless edges, or WebP for modern websites. A batch of mixed inputs can all be normalized to one size and one format in a single run. Cropping, rotation, and exact-dimension stretching are not part of this tool.
How to do it
- Use the button above to open the Image tool with resizing in focus.
- Add your photos — any mix of JPG, PNG, WebP, GIF, or BMP.
- Type a max width, a max height, or both; aspect ratio is kept automatically.
- Select the output format and adjust quality if you picked JPEG or WebP.
- Convert and download each resized file; the list shows the new pixel dimensions.
