FAQ — JPG to PNG Converter
Short answers to common questions. Click a question to reveal a concise answer.
Simply upload your JPG images (you can select multiple), and they will be automatically converted to PNG format in your browser. Then download individual files or use "DOWNLOAD ALL" for a ZIP containing all converted images. The entire process happens client-side for maximum privacy.
No. All conversion happens in your browser using JavaScript. Your image never leaves your device unless you explicitly share it elsewhere.
Images larger than 10MB are automatically skipped to ensure optimal browser performance. For best results, we recommend keeping images under 10MB. Very large images (over 4000x4000 pixels) may also cause performance issues or fail to convert due to browser canvas limitations. The conversion happens entirely in your browser's memory.
While there's no strict dimension limit in our code, very large images (typically over 4000x4000 pixels or 16+ megapixels) may fail to convert due to browser memory limitations. Most modern browsers can handle images up to about 4096x4096 pixels, but performance may be slow for extremely large images. If you have very high-resolution images, consider resizing them first or using a desktop image editor.
PNG is a lossless format, so the quality of the converted image will be preserved. However, since JPG is a lossy format, any artifacts present in the original JPG will also be in the PNG.
Yes! You can upload and convert multiple JPG images at once. Each image is processed individually and you can download them separately or use "DOWNLOAD ALL" to get a ZIP file with all converted PNGs.
After converting multiple images, click the "DOWNLOAD ALL" button that appears at the bottom. This creates a ZIP file containing all your converted PNG images, making it easy to download everything at once.
This converter specifically converts JPG and JPEG images to PNG format. Other image formats like PNG, GIF, WebP, etc. are not supported for conversion. Only upload JPG or JPEG files.
JPG images don't support transparency — they are always fully opaque. This converter simply converts JPG to PNG format while preserving the image data exactly as it is. PNG supports transparency, but since JPG doesn't contain transparency information, the converted PNG will also be fully opaque. If you need transparency, you'll need to add it using an image editor before conversion.
No, this converter does not provide background color options. JPG images are fully opaque and don't contain transparency. The converted PNG will maintain the same appearance as the original JPG. If you need transparency or background color options, consider using a more advanced image editor.
No, EXIF metadata is not retained during conversion. The browser's canvas API used for conversion does not preserve metadata like EXIF, GPS coordinates, or other embedded information. This is actually beneficial for privacy as it removes potentially sensitive location or camera data.
The converter works best in modern browsers: Chrome, Firefox, Edge, and Safari. Older browsers or mobile browsers may have limitations with memory or performance during conversion.
The conversion itself happens entirely in your browser without any server communication. However, you need an internet connection to initially load the webpage and JavaScript files. Once loaded, you could theoretically use it offline for subsequent conversions if your browser has cached the assets.
If you get an error, try a smaller file or a different browser. If the image is corrupted, re-export or try opening the file in an image editor first. Very large images (over 4000x4000 pixels) may also fail due to browser memory limits. You can contact support for persistent issues.
