Use the highest-quality JPG you have. Converting a small, repeatedly edited JPG to PNG will preserve its current artifacts, not restore the original pixels.
How to Convert JPG to PNG and Know When It Is the Better Format
JPG and PNG solve different image problems. JPG is usually smaller for photographs because it compresses continuous-tone detail efficiently. PNG preserves sharp edges and transparency more faithfully, which makes it a better fit for screenshots, logos, interface graphics, and images that will be edited again. Converting a JPG to PNG changes the container and encoding; it cannot recreate detail the JPG already discarded.

Open JPG to PNG
Select Valestiom's JPG to PNG Converter and choose the image. Processing stays in the browser, which is useful for screenshots or design assets you do not want to upload.
Check edges and color
Look at text, thin lines, and flat color areas in the output. PNG avoids adding another lossy pass, but it will not remove blockiness or ringing already present in the JPG.
Use the PNG for the right job
Download the result when you need transparency-friendly editing, sharp UI detail, or a lossless intermediate. Keep JPG for ordinary photo delivery when size matters more than editability.
When PNG is worth the larger file
PNG is a practical choice for screenshots, logos, diagrams, and interface captures because its lossless encoding keeps hard edges clean. It also supports an alpha channel, so an image can have transparent pixels around a subject instead of a baked-in background. Those benefits often outweigh the larger file size when the asset will be placed into another design or inspected closely.
For a photograph, conversion in the other direction is often more useful: JPG can make a camera image much smaller with little visible change at normal viewing size. Choose the format based on the next operation rather than treating PNG as a universal quality upgrade.
What conversion does not do
A JPG-to-PNG conversion does not restore transparency if the JPG has a solid background, recover text blurred by an earlier export, or increase the true detail of a low-resolution image. It simply decodes the JPG and writes those pixels into a lossless PNG representation.
If the output is still too large, resize it for the place it will appear or use a compressor designed for that format. If the issue is a visible background, use a background-removal workflow rather than expecting a format switch to infer which pixels should disappear.
Practical tips
- Use PNG as an editing intermediate when you expect several more saves and want to avoid additional JPG loss.
- Do not convert a photo to PNG just to make it smaller; PNG is commonly larger for photographic content.
- Keep the JPG beside the PNG until you know which version the destination accepts.
Frequently asked questions
Will JPG to PNG add transparency?
No. A JPG has no transparency channel to recover. The converter preserves the visible pixels and writes them as PNG.
Is PNG always higher quality than JPG?
PNG is lossless for the pixels it receives, while JPG is lossy. That makes PNG better for sharp graphics, but converting an already-compressed JPG cannot restore detail that is gone.
Why did the PNG become larger?
PNG is efficient for flat colors and hard edges, but photographs contain detail that PNG stores less compactly. A larger PNG is expected for many camera images.
