Tips for Better Compression
Use WebP for Best Compression

70-80% Quality is Optimal
For most photos, 70-80% quality provides excellent results with significant size savings.
JPG for Photos, PNG for Graphics
Use JPG/WebP for photographs and PNG for graphics, logos, and images with text.
Check the Preview
Always preview the compressed image to ensure quality meets your needs.
Consider the Use Case
Web thumbnails can use lower quality, while print images need higher quality settings.
Start with Original
For best results, compress from original high-resolution images rather than already-compressed ones.
Frequently Asked Questions About Image Compression
How much can I reduce my image file size?
Depending on the original format and quality settings, you can typically reduce file sizes by 40-80%. Photos with lots of detail compress better than graphics.
Will compressing my image reduce quality?
There's always a trade-off between size and quality. This Magica workflow lets you adjust the quality slider to find the perfect balance. At 70-80% quality, most images look nearly identical to the original.
Are my images uploaded to a server?
No! All compression happens directly in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy.
What's the best format for compression?
WebP typically offers the best compression for photos with the smallest file sizes. JPG is more universally compatible. PNG is best for graphics and images that need transparency.
Can I compress multiple images at once?
Currently, you can compress one image at a time. This allows for precise quality control on each image. We may add batch compression in the future.
Is there a file size limit?
There's no strict limit, but very large images (over 20MB) may be slow to process depending on your device. The tool works entirely in your browser.
Why is my PNG larger after compression?
PNG is a lossless format that doesn't compress as well as JPG or WebP. For smaller files, try converting to JPG or WebP instead.
What quality setting should I use?
For web use, 70-80% is usually ideal. For email attachments, 60-70% works well. For archival purposes, keep quality at 85% or higher.
Does this work offline?
Yes! Once the page is loaded, the compressor works completely offline since all processing happens in your browser.
Can I compress HEIC photos from iPhone?
Yes! We support HEIC format. Your iPhone photos will be converted and compressed automatically.
Is this tool free?
Yes, completely free with no limits. There's no signup required and no watermarks added.
What happens to image metadata (EXIF)?
Image metadata is removed during compression, which also helps reduce file size. This includes camera info, GPS data, and other metadata.
