PRACTICAL TOOL GUIDE
How to Resize Multiple Images Without Distorting Them
Batch resize JPG, PNG and WebP photos by percentage or maximum width, preserve aspect ratio and export a ZIP.
To resize multiple images consistently, select a batch, choose one maximum width or scaling percentage, and export new copies. Preserve aspect ratio to avoid stretching. Maximum-width mode keeps smaller images unchanged; percentage mode can enlarge them but does not add detail.
How to use the tool
- Keep originalsWork on exported copies so you can recover full-resolution originals later.
- Choose a size ruleFor website photos, try a maximum width of 1200 px. A 4000 × 3000 photo becomes 1200 × 900; a 600 × 400 image stays unchanged.Open the relevant tool →

Frequently asked questions
How do I batch resize without stretching?
Use a proportional scaling rule. Both dimensions change by the same ratio.
Can I resize to a fixed square?
Choose Same canvas dimensions for a square padded canvas. The image fits proportionally without cropping; use a separate crop workflow to fill a square edge to edge.
Are photos uploaded?
The processing flow uses browser canvas and local downloads; it does not upload source files.
