Convert JPG to Lossless PNG for Editing
Create broadly supported PNG working files from JPG photos without uploading them. Preserve the decoded pixels in a lossless format and convert entire batches on your device.
- Lossless PNG output after JPG decoding
- Same pixel dimensions as the source
- Private on-device batch processing
- Unlimited downloads with no watermark

Create a Stable PNG Working Copy
PNG uses lossless compression, making it a practical intermediate when a JPG must pass through graphics, annotation, or document workflows. Converting does not reverse compression already present in the JPG, but the PNG output avoids adding another lossy encoding pass. It keeps the decoded pixels and original dimensions ready for the next editing step.
Improve Compatibility with PNG-first Workflows
Some UI pipelines, presentation templates, developer tools, and image-processing scripts expect PNG input. Convert a JPG when a workflow rejects it or when a predictable lossless container is more convenient. The result opens in virtually every editor and browser, with no quality slider needed because PNG encoding is lossless. For any other format pair, the general Image Converter handles JPG, PNG, and WebP files up to 50MB in the same private way.
Keep Source Images Private During Batch Conversion
File decoding and PNG encoding happen locally in your browser. Add a folder of reference photos, scanned pages, or client images and convert them without placing copies on a remote server. Batch naming and ZIP download stay on the device too, and unlimited local conversion requires neither an account nor credits.
How to Convert JPG to PNG in 3 Steps
Select JPG files
Choose a single JPG or add a batch from your device. The browser loads each image locally with no upload step.
Convert to lossless PNG
The preset decodes the JPG and writes a PNG at the same dimensions. No output quality setting is required.
Save PNG results
Download each converted PNG or package the entire batch in one ZIP for the next editing workflow.
When JPG to PNG Is Useful
Annotate Screenshots and Photos
Create a PNG working file before adding text, arrows, shapes, or repeated edits that should not trigger another JPG compression pass. If only part of the frame matters, trim it first with the Image Cropper, which also runs in your browser.
Supply PNG-only Software
Convert references for development tools, upload widgets, or automated pipelines whose accepted input contract lists PNG but not JPG.
Standardize Mixed Project Assets
Turn a set of JPG inputs into consistently named PNG files and export one ZIP for a designer, developer, or documentation team.

Make Lossless PNG Working Copies
Convert JPG images privately for editing and PNG-only workflows. Same dimensions, no upload, no watermark, and unlimited batches. When the edited file is ready for the web, PNG to WebP produces a lighter delivery copy.
