Convert PNG to JPG
JPEG does not support transparency. Choose the background color that should replace transparent pixels. Processing happens in your browser; selected file contents are not uploaded.
Choose an image to begin.
How to use this tool safely
- Check that JPEG is accepted and decide which color should replace any transparent areas.
- Choose the PNG, set the background color, and convert it locally.
- Inspect the JPEG for halos, changed transparency, small-text artifacts, and final dimensions.
Input, output, and no-upload processing
Input must be PNG and output is JPEG. JPEG cannot represent transparency, so every transparent or semi-transparent pixel is composited onto the selected background.
What Readyvio verifies
The tool checks the JPEG output type and pixel dimensions. It does not verify a target file-size ceiling; use a maximum-KB tool afterward only if one is required.
Convert PNG to JPG with a chosen background
JPEG does not support transparency. Readyvio therefore lets you choose the color that replaces transparent and semi-transparent PNG pixels before creating the JPG locally in your browser.
The output keeps the decoded width and height, but JPEG encoding is lossy. Inspect logos, screenshots, diagrams, and small text carefully because sharp edges can develop artifacts.
Common questions
Why did transparent areas become solid?
Transparency is unsupported in JPEG. The background selector makes the replacement color explicit.
Can I convert without losing any quality?
JPEG encoding is lossy. Use a high-quality source and inspect sharp edges and text after conversion.
Does PNG to JPG make the file smaller?
Often for photographs, but not always. The result depends on the image content, dimensions, browser encoder, and transparency background.
Does the conversion preserve width and height?
Yes. Readyvio checks that the JPEG has the same decoded pixel dimensions as the PNG source.
Is my PNG uploaded?
No. Compositing and JPEG encoding happen locally in the browser.
Before you submit
The output uses lossy JPEG encoding. Inspect small text and sharp edges before use.
