Image Compressor FAQ
Is the image compressor free?
Yes, completely free. There is no signup, no watermark and no limit on how many images you can compress.
Does compression reduce image quality?
You control the quality with the slider. Lower quality creates smaller files with more compression, while higher quality keeps more detail. For best results, start at 80% and lower it until the image still looks good.
Which format gives the smallest file size?
WebP gives the best compression - typically 25-35% smaller than JPEG at the same visual quality. JPEG is best for photos and PNG for images that need transparency or sharp text.
Is my image uploaded to a server?
No. Compression runs entirely in your browser using the canvas API, so your image never leaves your device.
How do I compress an image to a specific size?
Lower the quality and reduce the maximum width until the compressed size falls below your target, such as 100KB or 1MB. The tool shows the exact compressed size instantly.
