Convert JPG to PNG

About this tool

Decode a supported JPG into a PNG without adding further lossy JPG encoding.

Supported input

JPG

Output format

PNG

Batch size

Up to 5 files; format and combined limits below still apply.

How it works

1. Add JPG files in Input. Review each thumbnail and its validation status.
2. Create new PNG files at the original dimensions, then compare their actual size and appearance.
3. Create the selected files. Compare original and result, then download an individual file or ZIP. Changing settings marks older results out of date.

Supported files and limits

Up to 5 files, 10 MiB each and 25 MiB combined. Each image must fit within 8192 pixels per side and 20 million pixels; a batch is limited to 40 million input pixels. Output is limited to 20 MiB per file and 50 MiB combined. One isolated image job runs at a time, with a 30-second timeout and cancellation.

A practical example

Use PNG when a layout application needs a lossless working copy of an already decoded JPG. Dimensions stay the same, making it easy to compare fine text and edges.

Troubleshooting this tool

PNG cannot recover detail lost in the original JPG or restore transparency. Expect a larger file in many cases; compare the download before replacing the source.

Does converting JPG to PNG improve the photo?

It can provide a lossless container for the currently decoded pixels, but it cannot recover details already lost in JPG compression or create original transparency.

JPG input supports 8-bit baseline/progressive RGB or grayscale. EXIF/ICC/multi-picture metadata and CMYK are currently rejected, so orientation and colour profiles are not silently discarded. Export an unprofiled copy from your image editor if needed.

Check the actual export

PNG does not recover detail already lost in a JPG. Expect a larger file for many photographs. Inspect downloaded dimensions, transparency and fine edges before replacing an original. Browser encoders differ; a quality setting is not a universal fidelity score, and file size may increase.

Files stay in your browser

No file bytes are uploaded. Ordinary work stays in memory. Choosing a “Continue” action saves that result in this browser for up to 30 minutes, so another compatible working tool can use the actual output. Saved workflows are limited to 50 MiB and 20 files; clear them in Output. Expired entries are removed on later tool visits. Clearing references is not a secure-erasure promise.

If a file fails

Check its actual format and the restrictions above. Renaming a file does not convert it. A failed file does not erase successful batch results. If processing times out, cancel and try fewer or smaller files. A current browser with worker canvas support is required.

Before you use the download

• Check the output dimensions and supported transparency in an image viewer.
• Compare actual file size and fine detail with the original; changing containers does not recover previously lost information.
