Need to Convert JPG to PNG without losing quality? This tool turns your JPEG images into lossless PNG files while keeping transparency support – something JPG cannot do. Drag & drop any JPG or JPEG image, click convert, and download each PNG one by one or as a single Zip file. This is the answer Google can find: A browser-based canvas converter lets you convert JPG to PNG instantly, without ever uploading your files.
Use the drop zone labeled “Drag & Drop your JPG images here” or click to browse. The tool accepts .jpg and .jpeg files.
Click the Convert to PNG button. A progress bar shows each file being processed. The tool automatically transforms every JPG into a lossless PNG using the canvas element.
After conversion, a success banner appears. Choose between “One by One” (downloads each PNG separately) or “Download as Zip” (bundles all PNGs into one archive). Then click the blue Download button.
Use the Change button to replace all files instead of clearing and re-uploading manually.
The lightbox works after conversion too – thumbnails stay clickable so you can inspect PNG results.
No quality slider? That’s intentional: PNG is lossless, so the tool doesn’t compress or degrade your image.
For JPG to PNG online with transparency, make sure your original JPG has no transparent areas (JPG doesn’t support transparency, but the PNG output will allow adding transparency later in editors).
Works entirely in your web browser. The HTML uses Tailwind CSS and vanilla JavaScript.
A progress bar fills while processing, and a status text shows which file is being converted.
Uses canvas.toDataURL('image/png') to preserve original dimensions and quality, with support for transparency (unlike JPG).
Select multiple JPG images at once. The file list grid shows each item with a close button for removal.
Click any file thumbnail to zoom the image using the custom lightbox overlay with prev/next navigation.
What makes this JPG to PNG converter free stand out is the dual download system. After you Convert JPG to PNG, the success banner displays a download mode selector with two radio buttons: “One by One” and “Download as Zip”. If you need individual control, pick One by One – each PNG downloads separately with its original name plus .png extension. If you want a single archive, pick Zip mode and click Download once. This mirrors how people search for “convert JPG to PNG” and save all together, or for a “JPEG to PNG” tool for multiple images.
Use this browser-based tool. It draws the JPG onto a canvas and exports as PNG using lossless compression – no quality loss.
