Choose fidelity, not just a smaller file

PNG stores the exported pixels losslessly. JPG and browser WebP exports may lose detail, even at quality 100. Keep the original; inspect small text and transparent edges. Conversion does not recover lost detail.

About this conversion

What this tool does

PNG and JPG solve different jobs. PNG keeps transparent pixels and is well suited to logos, interface graphics, and lossless working files. JPG is opaque and uses lossy compression, which makes it practical for photographs and systems that expect JPEG files.

Instructions

How to convert your file

1
Add one or more still images and check the preview names before converting.
2
Choose JPG for a compact opaque image or PNG for transparency and lossless output.
3
If you choose JPG, set the background that should replace transparent pixels and select a quality level.
4
Keep the original dimensions or enter maximum dimensions, then confirm the downloaded file's type, pixel dimensions, and treatment of transparent areas.

Settings

Choose the right export settings

JPG quality: Start around 90 for normal web photographs. Raise it for fine texture; lower it only after checking edges and gradients.
JPG background: JPG cannot store transparency. White is conventional, but a page or brand background can avoid an unwanted halo.
Resize: Maximum width and height keep the source aspect ratio. Reducing pixel dimensions usually saves more space than aggressive compression.
Sharpening: Use a small amount after downscaling. Strong settings can produce bright outlines around high-contrast edges.
Output check: Compare source and download at the same zoom. Verify width and height in file properties, then inspect formerly transparent edges on the exact background where the JPG will appear.

Example workflow

Example: preparing a transparent product cut-out

For a marketplace that requires JPG, choose the marketplace's page colour as the JPG background, keep enough pixels for its zoom view, and begin near quality 92. For a website that supports transparency, export PNG instead so the same cut-out can sit on different backgrounds.

Limitations

Before you download

Converting JPG to PNG stops further JPG compression but cannot restore detail already lost from the source.
Canvas-based export normally removes camera EXIF, embedded thumbnails, and most other file metadata.
Animated images are treated as still images; this workflow is not an animation converter.

FAQ

Questions about PNG / JPG

Will PNG transparency survive JPG export?

No. JPG has no alpha channel, so transparent areas are flattened onto the selected background colour.

Does changing JPG to PNG improve quality?

No. It changes the container and prevents another lossy save, but it cannot recreate detail missing from the JPG.

Why can the new file be larger?

PNG stores pixel data losslessly, so a photographic JPG converted to PNG is often much larger without looking better.
