Image compressor & resizer

Choose an image, set the size, then export and download.

Choose JPEG, PNG or WebP, up to 20 MB and 24 megapixels. Set both maximum dimensions and export. Proportions are preserved and small images are never enlarged. Animated inputs export one still frame. JPEG turns transparency white; PNG ignores quality. Export does not target an exact file size.

Processing stays in browser memory; files are not uploaded or saved in local storage. Compression may produce a larger file. Compare the preview and actual sizes. Re-encoding removes most metadata but is not a privacy guarantee; colors can change. Clear releases the preview. Large images may be slow on phones.
