Frequently Asked Questions
Why convert JPEG to PNG?
PNG uses lossless compression, which is ideal for images with text, logos, screenshots, or graphics that need crisp edges. JPEG artifacts disappear when re-saved as PNG.
Will the PNG be larger than the JPEG?
Usually yes — PNG is lossless so the file size is typically larger. However, for images with large areas of solid color (like screenshots), PNG can be smaller.
Does my image get uploaded anywhere?
No. The conversion runs entirely in your browser using the HTML5 Canvas API. Your files never leave your device.
Can I convert WebP or BMP files too?
Yes! The tool accepts any image format your browser can decode, including WebP, BMP, and GIF. The output is always lossless PNG.
JPEG vs PNG: When to Convert
| Reason | Why PNG is needed |
|---|---|
| Transparency | JPEG has no alpha channel; PNG supports full transparency for logos, icons, and UI elements. |
| Lossless editing | JPEG re-saves accumulate compression artefacts. Convert to PNG first for lossless round-trips. |
| Sharp edges | JPEG blurs edges and text. PNG is crisp for screenshots, diagrams, and screen-recorded UI. |
| Further processing | Editing a JPEG degrades quality further; PNG preserves original pixel values through editing. |
Note on Quality
Converting JPEG to PNG does not recover lost quality. JPEG is lossy: once compressed, the missing data is gone. PNG simply stores the existing pixel values losslessly. If the source JPEG has artefacts (blocky noise around edges), those artefacts will be preserved in the PNG output.
