Compression Tips
- Web use: 75–85% quality gives the best balance for websites and blogs.
- Social media: 80–90% quality preserves detail for platforms like Instagram and Facebook.
- Email attachments: 60–75% quality for smaller attachments that still look good.
- Archive storage: 90–100% quality for long-term storage with minimal quality loss.
Privacy & File Deletion
This tool runs entirely in your browser. Your images are never uploaded to our servers. Compression happens locally on your device, and the output file is generated client-side. No data leaves your browser.
Frequently Asked Questions
How much can I reduce the file size?
Results vary by image. Photos with lots of detail typically see 30–70% reduction. Simple graphics can see even more. You control the quality slider to balance size and appearance.
Is compression lossy or lossless?
At quality settings below 100, compression is lossy — some detail is removed to reduce file size. At quality 100 with WebP or PNG output, compression is effectively lossless. We recommend 80–90% quality for the best size-to-quality ratio.
Can I change the output format while compressing?
Yes. You can compress and convert to a different format in one step. For example, compress a PNG and output as WebP for maximum file size reduction.
Will the image dimensions change?
No. Compression reduces file size without changing pixel dimensions. If you also need to resize, use the Image Resizer tool first or after compression.
What formats are supported?
You can compress JPG (JPEG), PNG and WebP images. Output can be the same format or converted to any of the three.
What's the maximum file size?
Anonymous users can process files up to 25MB. Create a free account for files up to 50MB, or upgrade to Pro for 200MB.
