Choose a format for your image
Choose the format your destination accepts, then decide whether transparency or a smaller download matters most. This converter changes static JPG, PNG and WebP files while keeping their pixel dimensions. It does not resize images, remove backgrounds or restore lost detail.
| Format | Good fit | Transparency and quality |
|---|---|---|
| JPG | Photos for destinations that require JPG and do not need transparent areas. | Transparent pixels become white. Adjustable quality trades visual detail for file size. |
| PNG | Logos, screenshots and graphics where crisp edges or transparency matter. | Keeps transparency. No quality slider; photo files can be larger than JPG or WebP. |
| WebP | Photos or transparent graphics when the receiving website or app accepts WebP. | Keeps transparency and offers adjustable quality. Check the converted file size and appearance. |
Compare quality and file size after conversion
For JPG or WebP, start with the default quality and compare the input and output sizes shown in the queue. If the result is too large, lower quality and convert again, then inspect text, edges and smooth color areas in the downloaded file. Lower quality can introduce artifacts; changing the format alone does not guarantee a smaller file. PNG has no quality setting. Converting an already compressed JPG to PNG will not restore the details lost earlier.
Convert a batch and assign useful filenames
Add the images you want to process and choose one output format and quality setting for the queue. Enable Batch rename to set a prefix, a positive starting number and a separator. For example, prefix product, start 1 and a hyphen produce product-1.webp, product-2.webp and so on for WebP output. Without batch renaming, names are based on the original filenames with the new extension; conflicting output names receive a suffix. Check each generated name before downloading.
Download successful files or retry failed items
After conversion, each successful item has its own download button, and the ZIP contains the successful results in the current queue. A failed item does not need to prevent downloading the others. Read its error and retry after addressing the cause; for memory or size limits, try a smaller batch. Changing the output format or quality clears existing converted results, so run conversion again. A ZIP packages the images together; it does not promise additional image compression.
Frequently asked questions
Which input formats and batch sizes are supported?
Use static JPG/JPEG, PNG or WebP. Other formats and animated PNG/WebP are not supported. Each image must be no larger than 20 MiB, 16 megapixels and 16,384 pixels per side. A batch can contain up to 50 images and 200 MiB of input. Results together and the ZIP are each limited to 200 MiB; device memory can require smaller batches.
Does conversion upload my images or use credits?
No. Images are converted in your browser, with no account, credits or image upload required. Your source files remain unchanged. The page does not save results online, so download the files you need before refreshing or leaving.
Why is the background white after converting to JPG?
JPG cannot store transparency, so this tool fills transparent pixels with white. Choose PNG or WebP if you need to keep an existing transparent background. Converting a JPG back to PNG does not make its white background transparent.
Does conversion preserve orientation and camera metadata?
The tool applies the source image orientation during decoding and keeps the oriented pixel dimensions in the export. Original EXIF and GPS metadata are not copied. Keep the source file separately if your workflow needs camera or location information.
