Will converting JPG to PNG improve quality?

No. PNG stops further lossy re-encoding but cannot restore detail already lost in the original JPG compression.

Why convert JPG to PNG?

Useful when you need lossless re-saving during editing or compatibility with PNG-only tools.

Will the PNG have transparency?

No. JPG has no transparency information, so the PNG output is fully opaque.

Does this resize my image?

No. Exact original dimensions are preserved.

Yes. Upload multiple JPG files with independent previews and downloads.

Will PNG be larger than JPG?

Usually yes, especially for photos, because PNG is lossless.

Is conversion done on a server?

No. Everything runs locally via the canvas API.

Yes. Free on ToolifHub with no registration.

JPG to PNG Converter Free — Lossless Online

ToolifHub

Overview

JPG to PNG Converter on ToolifHub re-encodes JPG and JPEG photos as lossless PNG files entirely in your browser — preserving exact resolution without additional lossy compression steps during the conversion itself. Designers, developers, and editors use this when downstream tools require PNG input, when a lossless intermediate format is needed for multi-step editing, or when avoiding repeated JPG saves that accumulate artifacts. Batch support converts multiple files with thumbnail previews. Canvas-based export runs locally with no uploads. Important: converting cannot recover detail already discarded by the original JPG compression, and output PNGs remain opaque because JPG never stored transparency. Expect larger file sizes than the source JPG — PNG is lossless and typically bigger for photographic content. Chain with Image Compressor or WebP Converter when final delivery size matters.

About JPG to PNG Converter

JPG to PNG Converter is a free, browser-based tool on ToolifHub that converts JPG and JPEG images to lossless PNG format while preserving exact pixel dimensions. Batch upload, preview thumbnails, and download individually or all at once — entirely client-side.

Converting JPG to PNG stops further lossy re-compression going forward but cannot restore detail already lost in the original JPG. Output remains fully opaque — JPG sources contain no transparency data.

Convert back with the PNG to JPG Converter, or compress PNG outputs with the Image Compressor. Browse Image Tools or read our Privacy Policy.

Use Cases

Design software prep

Convert JPG photos to PNG before importing into tools that prefer lossless formats.

Avoiding repeated JPG saves

Use PNG as an intermediate format during multi-step editing to prevent cumulative quality loss.

Platform requirements

Meet upload requirements for systems that only accept PNG images.

Archiving before edits

Store a lossless PNG copy before performing further manipulations on important photos.

Examples

A 800 KB JPG may become a 2–4 MB PNG — larger on disk but stable for repeated edits without further JPG degradation.
Screenshots saved as JPG convert cleanly to PNG for documentation tools expecting lossless input.

Tips for Best Results

Convert to PNG when editing; convert back to JPG or WebP only for final web delivery.
Do not expect quality improvement — conversion preserves current pixels, not lost original detail.
Compress or convert to WebP after editing if the larger PNG size is a concern.

Limitations

Output PNGs are usually larger than source JPGs for photographic content.
No transparency is added — JPG sources are fully opaque.
Cannot recover quality lost before conversion.
Not ideal as a final web format when file size is the top priority.
