Large image files slow down websites, consume storage space, and take longer to share. Compressing images reduces file size while maintaining visual quality. This tool uses the Canvas API entirely in your browser — no uploads, no privacy concerns.
Frequently Asked Questions
What image formats are supported?
PNG, JPG/JPEG, WebP, and GIF images are supported. You can compress and convert between JPEG, PNG, and WebP.
Is my data private?
Yes. All compression happens in your browser using the Canvas API. No images are uploaded to any server.
What quality setting should I use?
For photos, 70-80 provides a good balance. For graphics with text, use 85-95. PNG is lossless so quality doesn't apply.
Why is my PNG file larger?
PNG is lossless. To reduce file size significantly, convert to JPEG or WebP which support lossy compression.
What are the size presets?
Social media presets auto-fill the width and height for common platforms like Instagram, Twitter, Facebook, and YouTube.
