Frequently Asked Questions
How do I compress an image for free?
Upload your image, adjust the quality slider to your preference, and click Download. The compression happens instantly in your browser — no upload, no waiting.
Which image formats can I compress?
You can compress JPEG, JPG, PNG, and WebP images. All formats are processed locally in your browser using the Canvas API.
Will compressing reduce my image quality?
Compression always involves some quality trade-off, but our tool gives you full control with a quality slider. For most images, 70–85% quality is barely noticeable but cuts file size significantly.
Is my image uploaded to a server?
No. Image compression runs entirely inside your browser using JavaScript and the Canvas API. Your images are never sent to any server — complete privacy guaranteed.
Is there a file size limit for compression?
There are no hard limits since everything runs locally. Very large images may take a few seconds depending on your device, but all images will be processed.
Is the image compressor completely free?
Yes, 100% free with no sign-up, no watermarks, no usage caps, and no hidden fees.
