Why Convert JPEG to PNG?
JPEG is a lossy format optimized for small file sizes, while PNG is a lossless format that preserves every pixel exactly. Converting JPEG to PNG doesn't restore lost data, but it prevents further quality degradation if the image will be edited or re-saved multiple times.
PNG is also the preferred format when you need a lossless archive, pixel-perfect screenshots, or compatibility with tools that require PNG input (such as some design software or print workflows).
How Our Converter Works
CheckTown's JPG to PNG converter runs entirely in your browser — no files are uploaded to any server:
- Upload a JPEG image (up to 50 MB) via drag-and-drop, file picker, or clipboard paste
- Click Convert — the image is decoded and re-encoded as lossless PNG with no further quality loss
- Download the PNG result and compare file sizes — PNG files are typically larger because every pixel is preserved

Convert JPG to PNG →When to Convert JPEG to PNG
JPEG-to-PNG conversion is useful in several scenarios:
- Editing workflows — save as PNG before editing to avoid stacking lossy compression artifacts each time you re-save
- Design tools — some applications or print services require PNG input for guaranteed quality
- Archiving — store a lossless copy of an image that will be modified, resized, or re-exported in the future
Frequently Asked Questions
Will the PNG file be larger than the original JPEG?
Almost always, yes. PNG preserves every pixel without lossy compression, so the file is naturally larger. This is expected and is the trade-off for lossless quality.
Does converting to PNG improve image quality?
No. The conversion preserves the current quality but cannot restore data that was already discarded by JPEG compression. It does, however, prevent further loss if you plan to edit and re-save the image.
Is my image uploaded to a server?
No. The conversion uses the browser's Canvas API. Your image never leaves your device.
