Tips & Notes
Get the best resize results.
Lock aspect ratio
Keeps width:height proportions intact. Change one dimension and the other auto-updates. Disable for exact custom sizes.
Choose the right format
JPEG — best for photos. PNG — best for graphics with transparency. WebP — smallest file size with great quality.
Quality slider
90% gives excellent quality at a smaller size. Below 70% you may notice loss. PNG ignores quality (always lossless).
100% Private
Images never leave your browser. Canvas API does all the work locally — zero server upload.
How to resize an image
Four simple steps — no account needed.
Upload image
Click or drag & drop a JPG, PNG, or WebP image onto the upload area.
Set dimensions
Enter target width and height. Enable aspect lock to prevent stretching.
Choose format & quality
Pick JPEG, PNG, or WebP. Adjust quality slider (90% is the sweet spot).
