Frequently Asked Questions (FAQ)

Which image formats can I compress?
This tool supports JPEG and PNG image formats for upload. All images will be converted to JPEG format after compression.
Are my images uploaded to a server?
No, all image processing and compression happens directly in your browser. Your images are not uploaded to any external servers, ensuring your privacy and data security.
How does the quality slider work?
The quality slider ranges from 0.05 (highest compression, lowest quality) to 1.0 (lowest compression, highest quality). Lower values will result in smaller file sizes but may reduce image detail. A common starting point is between 0.7 and 0.85 for a good balance.
Is there a file size limit for uploads?
Since processing is done in-browser, there are no strict server-side limits. However, very large images (e.g., over 20-30MB or extremely high resolution) may perform slowly or encounter browser memory limitations. Performance depends on your computer's resources.
Can I compress multiple images at once?
Currently, this tool processes one image at a time. For batch processing, you'll need to upload and compress each image individually.
Why do PNG images become JPEG after compression?
This tool is primarily a JPEG compressor. When you upload a PNG, it's drawn onto a canvas and then exported as a JPEG image using the selected quality setting. JPEG is a lossy format, which is why it can achieve high compression ratios, while PNG is typically lossless.
What quality setting is best?
There's no single "best" setting; it depends on your needs. For web use, qualities between 0.7 (70%) and 0.85 (85%) often provide a good balance of file size reduction without noticeable degradation in visual quality. Experiment with the slider to find the best setting for your specific image.
