Tips & Tricks

Efficient Compression

JPEG uses lossy compression to significantly reduce file size while maintaining good visual quality. Adjust the quality slider to balance between file size and image fidelity.

When to Use JPEG

Choose JPEG for photographs, social media images, and any content where small file size matters more than perfect pixel accuracy.

JPEG Best Practices

Use high quality (80-95%) for photos you want to keep; lower quality (30-60%) is acceptable for thumbnails or previews. Avoid re-saving JPEGs repeatedly as quality degrades each time.

Frequently Asked Questions

Are my images uploaded to a server?

No. All processing runs entirely in your browser via the Canvas API. Your images never leave your device.

How does JPEG compression affect quality?

JPEG uses lossy compression, which reduces file size by discarding less visible details. Higher quality settings (70-85%) retain good visual quality while significantly reducing file size. Very low quality (below 30%) produces visible artifacts.

Is there a file size limit?

Yes, each file must be under 50 MB. You can upload up to 20 files at once. If you need to convert more, process them in batches.

What JPEG quality is best for the web?

For most web use, a quality setting of 80-85% provides an excellent balance between file size and visual quality. For thumbnails or previews, 60-70% is often sufficient. For critical images, use 90-95% to minimize visible compression artifacts.

Can I convert multiple images at once?

Yes. Upload up to 20 images at once. After conversion, you can download each file individually or package them all as a ZIP archive for convenience.
