Compression tips by format
JPEG photos
Best for photographs. Quality reduction has minimal visual impact at 70–85%.
PNG graphics
Screenshots and illustrations. We auto-compare PNG vs JPEG output and use the smaller result.
WebP images
Modern format with excellent compression. Already well-optimized but we can reduce further.
Large images
Very high-resolution images are scaled down proportionally before quality reduction.
How to compress an image to under 1MB
Large image files can be a problem when uploading to websites, sending via email, or sharing on social media. Most platforms have file size limits between 1MB and 5MB. Whether you need to come down to 5MB, 2MB, 1MB, or even smaller, our free image compressor handles it without noticeable quality loss.
The tool uses a smart iterative algorithm: it starts at your selected quality level and progressively reduces quality until the file falls under 1MB. For photos, JPEG compression at 75–85% quality is virtually indistinguishable from the original. For PNG files containing graphics with flat colors (like screenshots or logos), we preserve the PNG format when it produces a smaller result.
All compression runs directly in your browser using Web Workers, so your images are never uploaded anywhere and the UI stays responsive throughout the process.
Frequently asked questions
What image formats are supported?
We support JPEG, PNG, WebP, GIF, and BMP. The compressor automatically selects the best output format to achieve the smallest file size while maintaining visual quality.
Will my image lose quality after compression?
Some quality reduction is expected, but the tool targets the highest quality possible within your size limit. For photos, JPEG compression at 75–85% is virtually indistinguishable from the original. You can adjust the target size and quality settings to find the right balance.
Is there a limit on how many images I can compress?
No. You can compress up to 20 images at once in a batch, and there are no daily or monthly limits. The tool is completely free with no sign-up required.
Are my images uploaded to a server?
No. All compression happens locally inside your browser using Web Workers. Your images never leave your device and are never sent to any server.
Can I compress to 2MB or 5MB instead of 1MB?
Yes. Use the target size control to set 5MB, 2MB, 1MB, or any other size. The compressor adjusts quality automatically to fit your chosen limit.
