- Enter the target width and/or height for your layout.
- Download the resized image.
- Optionally compress with Image Compressor or convert with JPG to PNG Converter.
Tips for sharper web images
Match the CSS display size (and 2× for retina when needed). Prefer resizing down, not up — upscaling invents pixels. After resizing, compress to cut file size further, then verify the asset still looks crisp on a real device.

Frequently Asked Questions
Should I resize before or after compressing?+
Resize to the display size first, then compress. Shrinking pixels removes more weight than compression alone on oversized camera uploads.
Will resizing crop my image?+
Resizing changes dimensions; preserve aspect ratio unless you intentionally crop. ToolVera lets you set width/height for common web targets.
Do images leave my device?+
Processing runs in the browser. You download the resized file locally without creating an account.
