FAQ

Common questions about image conversion and compression to help you use our tool better

Yes, our image converter and compressor is completely free. No account, no payment, no watermarks, no usage limits. All features are permanently free.
No. Our tool runs entirely locally in your browser using JavaScript and Canvas API. Your images never leave your device, fully protecting your privacy.
We support multiple formats including JPG, PNG, WebP, HEIC/HEIF and AVIF. You can batch convert and compress these into WebP or JPG output.
Just upload them. The tool automatically converts them to WebP or JPG and provides instant previews.
WebP is a modern image format developed by Google that can reduce file size by about 25-35% compared to JPG while maintaining the same image quality. If your images are mainly for web display, WebP is recommended. If you need broader compatibility (e.g., sending to users with older software), choose JPG.
Select or drag multiple images at once. They will be batch converted and compressed based on your settings, then packaged into a ZIP file.
We provide a 50% to 100% quality range. 80% quality usually offers a perfect balance between size and clarity. For high-quality needs, try 95% or above.
Max edge refers to the pixel value of the longest edge of the image. For example, if set to 1920, and the original image is 4000x3000, it will become 1920x1440 after compression (width scaled to 1920, height proportionally scaled). If not set, the original size is maintained and only compression is applied.
Adjust the quality slider or reduce the max edge size to control output size. WebP conversion typically has a higher compression ratio than JPG.
Yes. Enable 'Export Image Info' in 'More Settings'. An `images.json` file will be included in the ZIP, containing dimensions and full URLs for each image.
Once complete, click 'Download Image' or 'Download ZIP'. For multiple images, the system automatically packages them into a ZIP archive.
Yes. Our tool uses responsive design and can be used on phones, tablets, and computers. You can open the website directly in your mobile browser and upload photos from your album for compression.
Email attachments have size limits. We recommend converting to JPG, setting max edge to 1280 or 1920, and quality to 75-80% for best compatibility.
Choose WebP format, set max edge based on display needs (e.g., 1920px), and use 80% quality. This dramatically improves loading times and SEO rankings.
PNG images can be uploaded, but note: if output format is JPG, transparent areas will become white background. If transparency needs to be preserved, choose WebP format for output, as WebP also supports transparency.
