Convert JPG to PNG
Use this JPG-to-PNG converter when you need a lossless container for edits or annotations. It does not recover quality already lost in the source JPG, but it helps avoid extra degradation on every future save.

Supports HEIC, HEIF, WebP, PNG, JPG, AVIF, BMP
Known limitations
Before converting, note these constraints:
- Output behavior follows format capabilities (for example transparency support and lossy/lossless rules).
- Final file size depends on source image content and selected quality settings.
- If compatibility is critical, choose broadly supported targets first (typically JPG).

Frequently Asked Questions
How do I convert JPG to PNG online?
Drop your JPG files in, keep PNG as the output format, then download. PicShift runs entirely in your browser with batch support (up to 200 files per run) and no upload.
Does converting JPG to PNG improve quality?
No. Converting from JPG to PNG does not restore quality lost during JPG compression. However, converting to PNG prevents any further quality loss if you need to edit and re-save the image.
When is PNG better than staying on JPG?
Choose PNG when you need transparency, lossless intermediate files, or a workflow where you will save many times. Stay on JPG when you only need a small file to share or upload.
Will the PNG file be larger than the JPG?
Usually yes. PNG stores more image information and is less aggressive about discarding detail, so file size often increases — that is normal when you prioritize edit stability over size.
Why is the output file sometimes larger than the original?
The output file becomes larger for three clear reasons: (1) Converting from a lossy format (JPG, WebP) to a lossless format (PNG) preserves every pixel, so file size increases in exchange for zero quality loss. (2) AVIF uses the AV1 codec, which has encoding overhead for small or simple images. AVIF delivers its strongest compression gains on high-resolution photos, with 20–50% better compression than JPEG in benchmark comparisons. (3) If the source is already heavily compressed, re-encoding does not reduce size further. PicShift uses industry-leading WASM encoders (MozJPEG, OxiPNG, libwebp) to produce the smallest possible output at your chosen quality. In compress mode, PicShift automatically keeps the original file when compression increases size. Learn more: https://picshift.app/docs/size-increase-explainer/
