JPG to PNG converter
Make a PNG copy of a JPEG without changing its dimensions. PNG avoids another lossy export, but does not sharpen the source or remove its background.
Save the decoded image in a different format
JPG and JPEG normally identify the same image format. A PNG copy is useful when an editor requests PNG, when you want a broadly supported still-image intermediate, or when you need to avoid another JPEG export while comparing edits. The converter decodes the current JPEG and writes those rendered pixels into PNG. This is different from copying the original compressed stream. The new file can be much larger because PNG may preserve patterns and artifacts that JPEG already introduced.
Understand what cannot be recovered
JPEG compression may have discarded fine texture or introduced blocks and halos before this conversion begins. PNG does not reconstruct that information. It also does not make a photograph transparent: a normal JPEG is opaque, so its PNG copy remains opaque. For a cutout, use the background remover as a separate editing operation and inspect its mask. If an archived original or a higher-resolution camera file exists, start from that instead of hoping a new extension will improve the picture.
Choose a useful destination workflow
A PNG can be sensible for software that requires it, but it is not automatically the best website or email attachment. Compare the original and result at equal display size. Look for any unexpected orientation or color differences, then confirm the recipient accepts PNG and the actual byte size fits. The converter does not preserve every EXIF, ICC, or print-resolution field from the original. Keep the original for professional color-managed or archival work. Download this new copy under its .png extension rather than replacing your only JPEG.

How it works
Choose your JPG images
Select or drop up to 20 still images, 10 MB each and 100 MB combined. Every file is checked; originals are not overwritten.
Review the transparency limits
PNG has no lossy quality control here. Animation and original metadata are not preserved.
Convert and inspect
Process the queue, then select a file to inspect its original or converted preview at fit size or 100%. Retry errors separately; successful results remain available.
Save ready files or a ZIP
Download files individually or package ready results as a real ZIP. Duplicate names receive a number. Save outputs before clearing the queue or leaving the page.

PNG-only editor
Create the format required by a particular workflow, without inventing new detail.
Editing intermediate
Avoid another JPEG encoding pass while keeping a copy of the original.

Data retention
No automatic source or result saving; download the result before closing the tab.

- •No automatic backup, file-size promise, or upload-acceptance guarantee
Frequently asked.
No. Changing format cannot restore detail that was already lost. A higher-resolution source is the right starting point for a sharper result.
Only if the decoded source contains transparency, which a normal JPEG does not. This tool converts formats; it does not erase a background.
PNG uses different compression and preserves the decoded pixels without JPEG-style loss. Photographic detail and existing JPEG artifacts can make it expensive to encode.
Yes. .jpg and .jpeg use image/jpeg. The actual file must be a decodable JPEG, not another format whose name was changed.
No. This PNG workflow does not offer a lossy quality setting. Its result is not a promise of identical source metadata or original pre-JPEG detail.
No. Keep JPEG or test a WebP alternative for photographs when size matters. Use PNG when the destination or editing requirements justify it.

Why Converting JPG to PNG Does Not Restore Quality
Understand why a larger PNG cannot recover JPEG detail, how to compare equal-size images, and when a lossless-format copy still helps an editing workflow.
