How to export JPEGs as PNG images for an ecommerce gallery

Your product photos look right, but the store or workflow you use asks for PNG files. You can convert JPEGs without installing software, but changing the file format will not improve the original photo or make its background transparent.

Use the Image Converter to export up to 50 images as PNG in your browser. Then check the resulting files against your store's image requirements before adding them to a gallery.

Convert JPEGs to PNG

1. Open the Image Converter and select the JPEG images you want to prepare. Keep a copy of your originals in case you need to make a different version later.
2. Choose PNG as the output format. The converter supports JPG, PNG, WEBP, GIF, BMP, ICO, and TIFF files.
3. Add the rest of the product photos you want to convert, up to 50 images at once. If your gallery has a consistent naming pattern, check the file names before starting so the outputs are easy to match to their products.
4. Convert the images and save the PNG files to your device. The files are processed in your browser and stay on your device.
5. Open a few of the converted files and check their appearance, pixel dimensions, and file sizes. Compare them with the store's current image requirements before uploading the full set.

Choose the right format and image version

Use PNG when the workflow requires it

PNG is useful when a store, catalog system, or image workflow specifically requires PNG files. It also works well for graphics with sharp edges, such as product diagrams, labels, or images that include text. A PNG saves image data without adding another round of lossy JPEG compression.

Keep JPEG for ordinary product photos when allowed

For photographs, JPEG is often smaller than PNG at similar visible quality. Smaller files can upload faster and take up less storage. If your ecommerce platform accepts JPEG and does not require PNG, there may be no benefit to converting product photos. Check the platform's format and size limits first.

Expect the same pixels, not a higher-quality photo

Conversion does not add detail or increase the image's resolution. A JPEG has already been compressed, so the PNG contains the image as it looks now, including any compression artifacts. To get a sharper product photo, start with the original camera image or retake the picture, rather than converting the JPEG again.

Do not expect a transparent background

PNG can store transparency, but converting a JPEG does not remove its background. A white or colored background in the JPEG stays visible in the PNG. If your listing needs a cutout product image, remove the background in an image editor and export that edited result as PNG.

Fix common ecommerce image problems

1. Check the platform's requirements. Look up its accepted formats, maximum file size, minimum pixel dimensions, and image aspect ratio. Requirements vary by store, product type, and placement, so do not assume that one image size works everywhere.
2. Reduce oversized files carefully. PNG product photos can be much larger than their JPEG originals. If an image exceeds an upload limit, check whether JPEG is accepted for that listing. If PNG is required, reduce the pixel dimensions only if the platform permits it, and keep enough resolution for the product to remain clear when shoppers zoom in.
3. Match the gallery's crop and proportions. A square thumbnail may be displayed differently from a wide product image. Check the image's pixel dimensions and preview it in the listing layout. Do not stretch a photo to force it into a new shape, since that can make the product look distorted.
4. Make backgrounds consistent before converting. If one image has a gray background and another has a white one, changing both to PNG will not make them match. Edit the background before conversion, then inspect the edges around the product for leftover color or rough cutout marks.
5. Compare colors in the uploaded preview. A color can appear different across screens or after a store resizes and recompresses an image. Check the product in the actual gallery preview, especially when accurate color matters. Keep the original photo so you can create a replacement if the uploaded version looks wrong.
6. Keep a clear original-to-output match. Use consistent names that identify the product and view, such as blue-mug-front.png and blue-mug-side.png. Avoid replacing your original JPEGs with converted copies until you have confirmed that the PNGs uploaded correctly.

Prepare a consistent product gallery

Before converting a large set, test one front-facing image and one detail shot. Check that the product is centered, the background looks consistent, and the file meets the store's size and dimension limits. Once those examples look right in the listing preview, apply the same format and preparation steps to the remaining images.

Converting a file changes its format, not the truth of the product photo. Keep the images representative of the item shoppers will receive, and retain the originals until the gallery is live and checked.
