Image Compressor Quality and File Size
Keep every pixel, by default
Compression keeps your original pixel dimensions. Enable resizing in Advanced settings to reduce the longest edge proportionally, without enlarging smaller images.

Common questions
Image Compressor FAQ
Learn about supported formats, settings and how to compress image on your device.
Can this image compressor work without uploading files?
Yes. The image compressor decodes and encodes your image entirely in your browser. Compress images at their original dimensions or enable optional resizing; your file is not uploaded.
Why is the compressed file sometimes larger?
Your original may already be efficiently compressed. Changing formats or encoding at a higher quality can produce a larger file. The comparison reports the real result; lower the quality or dimensions to try again.
Does the quality slider work for PNG?
PNG export is lossless and does not use the quality slider. Reduce its dimensions or choose WebP or JPG to make a different size-versus-quality trade-off.
Are animation and metadata preserved?
No. Animated inputs become a single still image, and original EXIF and other metadata are not preserved. JPG flattens transparency onto your chosen background color.
Do I need an account, and are my files uploaded?
No account is needed. The selected file is processed locally in your browser and is not uploaded to a server. Your original remains unchanged. Download the result before refreshing or leaving the page.
What are the file limits?
One image at a time, up to 50 MB and 24 megapixels. Very large images can still exceed your browser’s memory or canvas limits. Try a smaller image if processing fails.
