How to compress images online
Three steps to make photos smaller for web, email and uploads — no install, no account.

Quality, format & resize
Quality slider
Controls compression for JPG and WEBP, and palette reduction for PNG. Lower values mean smaller files with more visible loss.
Output format
Keep the original format or convert to JPG, PNG or WEBP. WEBP usually gives the smallest files for photos.
Resize
Optionally cap the longest side (e.g. 1920px). Downscaling large photos is often the biggest size win.
Batch & savings
Compress a whole queue at once and see per-file and total savings before you download.

FAQ
How do I compress an image online for free?
Upload one or more images, set the quality and options, then click Compress All. Each smaller file downloads automatically — no account needed.
Which formats can I compress?
JPG, PNG and WEBP. You can keep the original format or convert while compressing.
Will compression reduce quality?
Lower quality produces smaller files with more visible loss, while higher quality keeps detail. Around 75–85% usually balances size and quality.
How do I shrink a PNG?
For PNG, lowering quality reduces the colour palette to cut file size. Set quality to 95%+ to keep it near-lossless.
Do you store my uploads?
No. Images are processed only for your compression request and are not kept as a public library.
