Image Resizer
Resize any image to exact pixel dimensions or a percentage - locally, with no upload.
About this tool
Resize images online without uploading them: pick exact pixel dimensions or a percentage, keep the aspect ratio locked, and download as PNG, JPEG or WebP. Everything is processed by your browser, which makes it fast and private - ideal for avatars, banners and listings with strict size requirements.
Does resizing reduce image quality?
Enlarging always costs some sharpness, but reducing size keeps images crisp. The tool renders at 92% quality, which is visually lossless for most uses.
What formats can I export?
PNG for lossless graphics, JPEG for photos, and WebP for the best size-to-quality ratio.
