Frequently Asked Questions
Everything you need to know about compressing images online
What is the maximum file size for mobile compression?▼
On mobile devices: Maximum 30MB per image file. For desktop browsers: Up to 200MB per image file. We recommend using desktop browsers for files larger than 30MB.
How many files can I compress at once on mobile?▼
Mobile: Up to 10 files at once. Desktop: Up to 50 files at once. For best performance on mobile, compress fewer files (3-5) if they're large (>10MB each).
Will the image quality be preserved during compression?▼
Yes, we use intelligent compression algorithms that reduce file size while maintaining visual quality. You can adjust the compression quality using the slider. On mobile, quality is limited to 70% max for better performance.
Can I compress PNG files with transparency?▼
Yes, PNG files with transparency (alpha channel) are supported. During compression to JPG, transparent areas will be converted to white background as JPG format does not support transparency.
How do I download compressed files?▼
You can download files individually by clicking the download button on each image, or download all files at once as a ZIP archive using the "Download as ZIP" button.
Is the compression secure? Are my files uploaded to your servers?▼
All compression happens directly in your browser (client-side). Your images are never uploaded to any server, ensuring complete privacy and security.
Why does compression fail on mobile for large files?▼
Mobile devices have limited memory and processing power. Files larger than 30MB may exceed the available memory. Use desktop browsers for large files or compress your images in smaller batches.
What image formats are supported?▼
We support JPG, JPEG, and PNG formats. Other image formats like WebP, BMP, or TIFF are not supported. PNG files are automatically converted to JPG during compression for better size reduction.
