How much can I reduce my image size?

Most camera photos shrink by 60–80% at quality 80 with no visible difference. Converting to WebP adds another 25–50% savings compared to JPG.

What is the best output format?

WebP offers the best size-to-quality ratio for web use. JPG is best for maximum compatibility. PNG is ideal when you need lossless quality or transparency.

Can I resize and compress at the same time?

Yes. Set a maximum dimension (e.g., 1920px) and the image will be scaled down proportionally before compression, combining both savings.

Will it strip EXIF metadata?

Yes. The re-encoding process removes EXIF data (camera info, GPS coordinates, etc.), which also saves a few kilobytes and protects your privacy.

Can I compress PNG files?

Yes. You can compress PNG images by converting them to WebP or JPG for significant size reduction, or keep them as PNG for lossless output.

What is lossy vs. lossless compression?

Lossy compression (JPG) reduces file size by discarding some image detail. Lossless compression (PNG) reduces size without any quality loss but achieves smaller reductions.

How much can I reduce file size?

Typically 50-80% for JPG images. Results vary based on image content, original quality, and the compression level you choose.

Will compression affect print quality?

At quality 70-80%, the difference is rarely visible in prints. Below 50% quality, pixelation may become noticeable in large prints.

How image compression works

FileKit decodes each image with the browser's native image decoder, optionally resizes it, then re-encodes it at the chosen quality. JPG and WebP at quality 80 typically produce files 60–80% smaller than camera originals at no visible quality loss. PNG output is always lossless. For batch processing, the original aspect ratio is preserved and a white background is added under transparency when converting to JPG.

How to Compress Images

1
Upload your images
Drag and drop one or more images (JPG, PNG, WebP). FileKit processes them entirely in your browser.
2
Adjust quality
Use the quality slider to balance file size and visual quality. Lower values produce smaller files with more compression artifacts.
3
Download compressed images
FileKit shows the original and compressed sizes for each image. Download individually or all at once.
