Frequently Asked Questions
Will my image quality get worse?+
At 70–85% quality the difference is almost impossible to see, while the file becomes far smaller. Lower values reduce size more but may show blur.
Which format compresses best?+
WEBP is usually smallest, JPG is great for photos, and PNG is best for graphics with sharp edges or transparency.
Is there a file size limit?+
No server limit, but very large images depend on your device memory. Images up to around 20 MB work fine on most devices.
Is my data safe?+
Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
Is this tool really free?+
Yes — completely free, no signup, no watermark and no usage limit.
