How to use
What is this tool for?
Resize and convert multiple images locally in the browser — handy when you need consistent dimensions or quick WEBP/JPEG/PNG exports without installing desktop apps.
Suggested workflow
- Add images via “Select images” or drag-and-drop (multiple files supported).
- Set target width/height, resize mode, output format, and optional filename prefix/suffix.
- Click “Process images” and review results in the right panel.
- Download individual outputs or use “Download ZIP” to fetch everything at once.
Resize modes
- Stretch: forces the image to the exact target size and may distort.
- Cover: preserves aspect ratio, fills the canvas, and crops overflow.
- Contain: preserves aspect ratio and fits the whole image; empty margins may appear.
Output formats
- WEBP: great compression with good visual quality for most web use cases.
- JPEG: common for photos; no transparency.
- PNG: supports transparency; good for icons and assets with alpha.
- Keep original: tries to preserve the original type (subject to browser support).
Tips
- For uniform product thumbnails, pick a target aspect ratio first, then choose Cover or Contain.
- Use the quality slider to balance file size vs clarity for JPEG/WEBP.
- Prefix is prepended and suffix is appended before the extension. Both are optional; defaults keep the original base name.
