About JPG to PNG conversion
PNG uses lossless compression, meaning every pixel is stored exactly as-is. When you convert a JPG to PNG the result is a perfect snapshot of your JPEG - No further compression artefacts can accumulate, though quality lost in the original JPEG encoding is not recovered. This makes JPG→PNG useful as an archival step when you plan to make further edits and want to avoid a second round of lossy re-encoding.
The most common reason to convert JPG to PNG is to gain proper transparency support. PNG allows pixels to be partially or fully transparent, enabling clean compositing on web pages, UI design, and print workflows. Note that your existing JPG background colour will remain after conversion - You will need to erase it in an image editor to make it truly transparent.
PNG files are typically 3–5× larger than equivalent JPGs. If file size is a priority and transparency is not needed, WebP is a better destination - It delivers lossless compression at roughly the same size as a JPEG. Use PNG when pixel-perfect reproduction, transparency, or crisp text edges are the priority.
Where PNG comes from
PNG (Portable Network Graphics) was created in 1996 by a working group led by Thomas Boutell as a patent-free replacement for GIF after Unisys began enforcing its LZW patent on CompuServe's format. The W3C published it as a Recommendation in 1996 and ISO/IEC 15948 standardized it in 2003. PNG-24 added full alpha transparency that GIF's 1-bit mask could not match, and APNG (2008) later bolted on animation. Today PNG is the default screenshot format on macOS, Windows 11 Snipping Tool, and iOS, and remains the go-to format for logos, UI mockups, and any raster asset that must preserve crisp edges on a transparent background.
JPG vs PNG at a glance
| JPG | PNG | |
|---|---|---|
| Compression | Lossy DCT (baseline JPEG) | Lossless DEFLATE |
| Transparency | None (8-bit RGB only) | Full 8-bit alpha channel |
| Typical file size (12 MP photo) | 2-4 MB at Q85 | 12-25 MB (3-6x larger) |
| Best for | Photographs, gradients | Screenshots, logos, UI assets |
| Bit depth | 8 bits/channel (24-bit color) | Up to 16 bits/channel (48-bit color) |

- Export the JPG logo from the client's PDF deck at full resolution (around 1600x1600).
- Convert JPG to PNG so the white box around the wordmark can later be made transparent.
- Open the PNG in Photoshop and use Select > Color Range on the white background, feather 1 px.
- Delete the selection, save as PNG-24 with alpha; final file lands near 180 KB.
- Drop the transparent PNG onto a dark website hero to confirm there is no halo or JPG ringing.
Recommended conversion settings
| Use case | Settings |
|---|---|
| Logo or icon for a website | PNG-24 with alpha, no interlace, 8-bit per channel |
| Screenshot for documentation | PNG-8 indexed (256 colors) to cut size 60% |
| Archival master from a JPG scan | PNG-48 (16-bit), embed sRGB profile |
| Email signature graphic | PNG-24, max 600 px wide, under 100 KB |
| Print-ready transparent overlay | PNG-24 at 300 DPI, embed ICC profile |

When to convert JPG to PNG
The most common reason to convert JPG to PNG is to enable transparency. JPG does not support an alpha channel, so any time you need a logo, product photo, or graphic that sits on a coloured or patterned background without a white box around it, PNG is the correct format. Graphic designers routinely convert product images to PNG so they can overlay them cleanly on website banners, social media posts, and presentation slides.
PNG also uses lossless compression, which means every pixel is reproduced exactly as it was in the original. This matters when you need to re-edit the image later - Each save in JPG degrades quality slightly, whereas saving to PNG and back is always safe. Developers working on UI assets, icons, and screenshots prefer PNG for this reason.
If you are uploading to a design tool such as Figma, Canva, or Adobe Express and notice a white background appearing where you expected transparency, the source file is almost certainly a JPG. Converting to PNG first solves the problem instantly.
JPG to PNG tips
- Use PNG for screenshots, UI mockups, and any image containing sharp text or lines -PNG preserves the crisp edges that JPEG would blur into coloured halos.
- For photos and hero images on websites, avoid PNG - The larger file size slows page loads. Keep photos as JPG or convert to WebP.
- Strip EXIF metadata before converting - It slightly reduces PNG file size and removes GPS coordinates and camera data from the output.
- If you need a transparent background, convert to PNG first, then open the file in GIMP, Photoshop, or an online background-remover tool to erase the background.
- When sending PNG files by email, check the file size - A single PNG can easily exceed 5 MB. Resize the image to the required display dimensions before converting.

JPG to PNG tips
- PNG is the right choice when you need transparency or plan to edit the image further — use JPG for photos you're done editing.
- PNG files are typically 3–5× larger than JPG for the same photo — only convert when transparency or lossless quality is genuinely needed.
- For logos and graphics with flat colors, PNG compression is very efficient; for photos it produces unnecessarily large files.
