Convert JPG to PNG – Switch to Lossless When Quality Matters
JPG (JPEG) is excellent for photographs but uses lossy compression — every time you save a JPEG, some image data is permanently discarded. PNG, by contrast, is a lossless format: it stores every single pixel exactly, with no quality degradation on save. This makes PNG the right format whenever you need to edit an image repeatedly, use it in a design workflow, or display it with a transparent background.
The most common reason to convert JPG to PNG is when you're working with an image in a design tool like Photoshop, Figma, or Canva and you plan to add a transparent background, overlay it on a design, or save it multiple times. Using PNG in these workflows prevents the compounding quality loss that happens when you repeatedly edit and re-save a JPEG.
This converter does it entirely in your browser. Drop in a JPG, get back a PNG — in seconds, with zero upload, zero loss, and zero account required.
How to Convert JPG to PNG Online – Step by Step
- Upload your JPG — Drop a .jpg or .jpeg file onto the dropzone, or click to browse.
- Select PNG as output — PNG is selected by default for lossless output. You can also output as WEBP or PDF from the format selector.
- Click Convert to PNG — The browser loads the JPEG, decodes it via the Canvas API, and re-encodes it as lossless PNG.
- Preview and download — Your PNG is ready. Click Download PNG to save it locally.
When Should You Convert JPG to PNG?
Design & Editing Workflows
When working in Photoshop, Figma, or Canva, save as PNG to avoid generation loss across multiple save cycles. PNG will not degrade no matter how many times you open and re-save it.
Logos & Branded Assets
Logos need crisp edges and transparent backgrounds. Converting to PNG and then removing the background in a design tool gives you a clean asset with no JPEG artifacts around edges.
Charts, Screenshots & Text Images
JPEG compression destroys the sharp edges in screenshots and infographics. PNG preserves these perfectly. Any image with crisp text or thin lines should be stored as PNG.
Web Assets & UI Elements
UI icons, buttons, illustrations, and web UI components work better as PNG or SVG. Converting from JPG to PNG before embedding in a website removes compression artifacts.
Key Features
- Zero quality loss — PNG is lossless. The output PNG pixel data is identical to the decoded JPEG source.
- Multi-format output — Also converts to WEBP and PDF. Use the format selector in the controls panel.
- Works with all JPEG variants — Accepts .jpg and .jpeg files regardless of the source (camera, screenshot, downloaded).
- 100% browser-based — No file upload. All conversion runs inside your browser via Canvas API.
- Quality slider for WEBP/JPG output — If you choose WEBP or JPG output instead of PNG, the quality slider gives you control over the compression level.
🔒 Your Files Never Leave Your Browser
The JPEG file is loaded into memory via the FileReader API, decoded onto an off-screen Canvas, and re-encoded as PNG. The Canvas's PNG encoding is lossless by definition — every pixel of the decoded JPEG is stored exactly in the output PNG. No network request is made during this process. The tool works identically offline.
- Input: JPG / JPEG

Frequently Asked Questions
Tips for JPG to PNG Conversion
- Don't convert for web performance — use WebP instead. PNG files are larger than JPEG and will slow down your website. For web use, convert JPG to WebP instead.
- Use PNG for any image you'll edit in design software. Opening and re-saving a PNG in Photoshop or Canva never degrades quality. JPEG re-saves do.
- For background removal, PNG is required. Transparent pixels can only be stored in formats that support alpha channels — PNG and WebP. JPEG cannot store transparency at all.
