What is an Image Compressor?
An image compressor reduces the file size of images while maintaining acceptable visual quality. This is essential for web performance — smaller images mean faster page load times, lower bandwidth usage, and better SEO rankings. Our free online image compressor uses client-side canvas processing to reduce JPEG, PNG, and WebP file sizes by 50-80% without noticeable quality loss. Everything runs in your browser — your images are never uploaded to any server.

Frequently Asked Questions
How much can images be compressed?
Typical compression reduces file size by 50-80%. A 5MB photo can often be compressed to under 1MB with minimal visible quality loss. The exact reduction depends on the image content and chosen quality level.
Is this like TinyPNG?
Yes! DevDeck Image Compressor works similarly to TinyPNG and Squoosh, but with one crucial difference: your images are never uploaded to a server. All compression happens locally in your browser.
Does compression affect image dimensions?
No. Compression reduces file size without changing the image's width or height. If you also need to resize, use our Image Resizer tool.
Which format compresses best?
WebP generally achieves the best compression ratios, followed by JPEG. PNG files tend to be larger because PNG uses lossless compression. For photos, converting to WebP or JPEG usually produces the smallest files.
Why Use DevDeck?
TinyPNG, Squoosh, and other compressors upload your images to their servers. DevDeck compresses everything in your browser using the Canvas API — your photos, screenshots, and design files never leave your device.
