Sometimes a tool, a template or a print service asks for PNG and all you have is a JPG. This converter turns JPG and JPEG files into PNG in your browser, in batches, with a ZIP download. Before you convert, it helps to know exactly what the new file will and will not give you, because the most common reasons people search for this conversion are based on two myths.
Your images are processed on your own device and never uploaded to a server.
How to convert JPG to PNG
- Drag your .jpg or .jpeg files into the box at the top of this page, or click it to select them.
- Choose PNG as the output. There is no quality slider for PNG, because PNG is lossless and keeps every pixel.
- Convert the files. Expect each PNG to be larger than the JPG it came from.
- Download each PNG, or the whole batch as a ZIP.
What converting to PNG does not do
It does not add transparency
A JPG has no transparent pixels. The white or colored background in the photo is real image data, and it stays exactly where it is in the PNG. To get a transparent background, you need to remove the background in an image editor or a background removal tool, then save as PNG. Converting the format alone changes nothing about what is in the picture.
It does not restore quality
JPG compression discards detail when the file is saved. The blocky artifacts, color banding and smudged textures are baked into the pixels. PNG stores those pixels losslessly, artifacts included. The PNG is an exact copy of the JPG as it is now, not of the original photo before it was compressed.
It usually makes the file bigger
Lossless compression cannot shrink photographic detail the way JPG does, so a photo converted to PNG often grows to several times its JPG size. That is expected, not a fault.
When PNG is actually useful
- Editing in several rounds. Every time you open and save a JPG, it is compressed again and loses a little more. Convert once to PNG, do all your edits, then export a final JPG at the end.
- Adding text, arrows or overlays. Sharp edges and small text stay crisp in PNG. If you are building a size chart, a feature graphic or an infographic for a listing, save the finished graphic as PNG.
- Preparing for background removal. Many editors export cutouts as PNG so the transparency survives. Starting from a PNG avoids an extra round of JPG compression.
- Tools that require PNG. Some templates, print on demand design uploads and app icon fields only accept PNG.
Quality and file size
PNG output keeps every pixel of the decoded JPG, so the visual quality is identical to the JPG you started with. What changes is the file size, and on photos it goes up. For a web page or a marketplace listing, that extra weight buys nothing, so upload the JPG unless the platform asks for PNG.
If the JPG is large in pixels, reduce it with the image resizer first. Converting a 4000 pixel photo to PNG produces a very heavy file that most upload forms will reject or slow down.
JPG vs PNG vs WebP
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes | Yes |
| Quality loss on each save | Yes | No | Yes in lossy mode |
| File size for photos | Small | Large | Smallest |
| Best for | Final photos for upload | Editing copies, graphics, text | Images on your own website |
Tips for store and marketplace images
- Shopify says PNG is the best file type for most product images, followed by JPEG. That holds when the PNG comes from an original, high quality source. A PNG made from a JPG offers no quality benefit over uploading the JPG itself.
- Etsy accepts PNG, but not transparent PNG: its help center says transparent areas appear black. If you removed a background, fill it before uploading, or use the PNG to JPG converter with a white background.
- Amazon accepts PNG, but the main image still needs a pure white background (RGB 255, 255, 255), and JPEG is its preferred format.
- Graphics belong in PNG. Size charts, care instructions and comparison graphics with text look sharper as PNG, so export them that way from the start.
If your product images arrive from supplier stores, the AM Jarvis Product Importer copies them into your Shopify or WooCommerce store with the variants and prices, and you only need to convert the graphics you create yourself. See the guide to importing products to Shopify for the full process.
Converting JPG to PNG on a Mac or Windows PC
On a Mac, open the JPG in Preview, choose File > Export and pick PNG. On Windows, open it in Paint and use File > Save as > PNG picture. Both work for single files. For a batch, drop them all here and download one ZIP. The converter saves full-color PNG, which is right for photos. Logos and flat graphics with few colors can be made much smaller afterward with a PNG optimizer that reduces the color palette.
A worked example
You are building a size chart for a listing from a 1600 x 1200 JPG photo of a garment. Convert it to PNG here once, add your text and measurements in your editor, save as many times as you like without extra loss, and export the finished chart as PNG, where the text stays sharp. Upload the plain lifestyle photos as JPG. If a print on demand service asks for PNG, convert the final design here and check it is at least the pixel size they require, since conversion does not add pixels.
Keeping a PNG a PNG when you share it
Many apps quietly convert images when you send them. WhatsApp compresses anything sent as a photo into a smaller JPG, which is why a PNG can arrive as a JPG; send it as a document instead to keep the original file. Social networks such as Facebook and Instagram re-encode uploads too. Email attachments and cloud links (Google Drive, Dropbox) keep the file exactly as it is, so use those when the recipient needs the real PNG, for example a print shop or a designer.
Who uses this converter
- Print on demand sellers whose design upload fields accept only PNG.
- Designers and marketers making editable master copies before adding text or overlays.
- App and web developers who need PNG for icons or asset pipelines.
- Students and office users meeting a form that asks for PNG.
Troubleshooting
- The PNG is several times larger. Expected for photos. Upload the JPG unless PNG is required.
- The background is still white. Conversion does not remove backgrounds. Use a background removal tool, then save as PNG.
- The image looks blocky. The artifacts were already in the JPG. Start from a better original if you have one.
- Batch limit. Up to 300 files per batch, with a ZIP download at the end.
Privacy
All conversion happens in your browser. Your JPG files are processed on your own device and are never uploaded to a server. The PNG files do not carry over the JPG's EXIF metadata, so details such as the camera model, capture date and GPS location are left out.
Tip: Keep a folder of PNG masters for images you edit often, and export fresh JPGs from them. It stops the quality loss that comes from re-saving the same JPG again and again.
