Frequently Asked Questions (FAQ)

What image formats can I compress?
This tool supports JPEG and PNG image formats for uploading. All images will be converted to JPEG format upon compression.
Are my images uploaded to a server?
No, all image processing and compression happen directly in your web browser. Your images are not uploaded to any external server, 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). A lower value will result in a smaller file size but may reduce image detail. A common starting point is around 0.7 to 0.85 for a good balance.
Is there a file size limit for uploads?
Since processing is done in your browser, there's no strict server-side limit. However, very large images (e.g., over 20-30MB or extremely high resolutions) might perform slowly or encounter browser memory limitations. Performance depends on your computer's resources.
Can I compress multiple images at once (batch processing)?
Currently, this tool processes one image at a time. For batch processing, you would need to upload and compress each image individually.
Why might a PNG image become a 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. If you need to keep the PNG format with lossless compression, this tool will convert it to JPEG.
What is the best quality setting to use?
There's no single "best" setting; it depends on your needs. For web use, a quality between 0.7 (70%) and 0.85 (85%) often provides a good balance between file size reduction and visual quality. Experiment with the slider to find what works best for your specific image.
