About this tool
Heavy images are the top cause of slow pages, and slow pages lose visitors and rankings. This compressor shrinks JPG, PNG and WebP files right in your browser using the same canvas encoders your operating system relies on — no upload queue, no per-image fee, no privacy leak. Drag in a batch of photos, set the quality slider, and watch each image recompress with a live before-and-after size readout so you can see exactly how many kilobytes you saved. A max-dimension option downsizes oversized camera shots in the same pass, because a 6000-pixel photo displayed at 800 pixels is wasted bandwidth no codec can fix. WEBP output typically cuts another 25 to 35 percent versus JPEG at the same visual quality. Download results individually or as a batch. Since processing is local, it is ideal for client work, unreleased product shots, or personal photos you would rather not hand to a third-party server. Faster pages, smaller emails, happier users.
How to use Image Compressor
- Drop one or more images onto the upload area.

- Press Compress and watch the per-image savings report.
- Download the compressed images individually or all at once.
Frequently asked questions
Which formats are supported?
JPEG, PNG and WebP input, with JPEG or WebP output. WebP usually gives the smallest files at equal quality.
Does compression happen on your servers?
No. Everything runs in your browser with the canvas API — your images never leave your device.
What quality setting should I use?
80 is a great default for photos: typically 60-80% smaller with no visible difference. Go lower for thumbnails, higher for hero images.
Is there a limit on image count or size?
No hard limit. Dozens of images per batch work fine; very large photos just take a few seconds each to process locally.
