Convert JPG photos to PNG for editing, design work or systems that require PNG. Free in your browser — no sign-up, no watermarks.
How to convert JPG to PNG
- Click Choose files (or drag & drop) and select one or more JPG files. You can also paste an image from your clipboard.
- No settings needed for this conversion — the defaults handle everything.
- Press Convert to PNG. Each file is converted with a live progress indicator.
- Open the download page to save your files individually or grab everything as a single ZIP.
Why convert JPG to PNG?
Many upload forms, design tools and print-on-demand services insist on PNG. Converting JPG to PNG produces a lossless copy that will not degrade with further saves — ideal before repeated editing. Note that PNG cannot add transparency to a photo that never had it; for cutting out backgrounds you still need an editor.

What this tool preserves — and what it changes
✓ Preserved
- Every decoded pixel exactly — the PNG encode is lossless, so nothing further is lost after the JPG is read
- Dimensions — no resampling happens
↺ Changed
- The JPG's existing compression artifacts are preserved faithfully, not removed — lossless from here on does not mean restored
- File size typically grows several-fold: PNG cannot compress photographic noise the way JPEG does
- EXIF metadata is dropped by the re-encode
Known limits & edge cases
- No transparency appears: the JPG never had an alpha channel, so the PNG comes out fully opaque
- A 'JPG' that is really a renamed PNG or WebP is decoded by its real content and flagged on the inspection card
Engine: Your browser's own image decoder and canvas encoders (AVIF included); HEIC decodes via a bundled JavaScript decoder (Emscripten-compiled libheif); GIF, BMP and ICO are written by our own encoders. These statements describe the engine as shipped on 2026-10-02 — behaviour changes are recorded in the changelog.

What converting to PNG does — and doesn’t — do
An honest note first: converting a JPG to PNG does not restore quality the JPG compression already discarded. What it does is stop further loss. From this point on, the image can be opened, edited and re-saved any number of times with zero additional degradation — which is exactly what you want before annotating a screenshot, tracing a logo, or making repeated edits in a picture editor that would otherwise re-compress a JPG on every save.
PNG is also the format many tools demand for specific jobs: alpha-capable editors, sprite pipelines, icon generators and some print workflows accept only lossless input. Expect the file to grow — a photograph re-wrapped as PNG is commonly 5–10× larger, since lossless compression can’t exploit the shortcuts JPG takes. For photos that will simply be viewed, JPG remains the better carrier; convert when editing begins.
Frequently asked questions
Is this JPG to PNG converter free?
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Can I convert multiple JPG files at once?
Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
Will I lose quality converting JPG to PNG?
No — PNG is a lossless format, so the converted file reproduces the decoded image pixel for pixel. No additional compression artifacts are introduced by the conversion.
