Why convert JPG to PNG?
JPG compresses photographs aggressively by discarding high-frequency detail the eye doesn't usually notice — but that compression is one-way. Once JPG artifacts are in the file, no conversion can restore the original pixels. What converting JPG to PNG does do is give you a lossless container for whatever the JPG currently holds, which means subsequent edits and re-saves won't introduce new compression noise. That's the right move when you're about to do heavy editing, composite the image with a transparent alpha channel, or hand off to a tool that expects PNG. Expect the output file to be roughly 3-10x larger than the JPG source.
Protect against further degradation
JPG is lossy on every save. If you plan to crop, retouch, or composite the image repeatedly, converting to PNG first locks in the current state and prevents compounding compression artifacts with each round-trip.
Enable transparency
JPG has no alpha channel. Converting to PNG gives you a container that supports transparent pixels — useful when you need to mask out a background or composite the image onto a new canvas in your editor.
Editor compatibility
Some design and vector tools prefer PNG input over JPG for asset workflows. Converting ahead of time avoids surprise re-encodes inside the editor.
When JPG to PNG is the right call
Converting to PNG is a forward-protection move, not a quality-recovery move.
Heavy editing ahead: PNG freezes the current state before further work degrades it.
Transparency work: PNG's alpha channel lets you mask out backgrounds.
Handoff to tools that require or prefer PNG: design software, vector tools, some CMSs.
When file size isn't the constraint: PNGs are typically 3-10x larger than the JPG source.

What you get
Every conversion here runs on a temporary copy, delivers a ready download, and clears out quickly after you’re done.
- Lossless PNG output — no new compression artifacts introduced during conversion.
- PNG is ready for transparency editing (cut-outs, soft masks, anti-aliased edges).
- Preserves whatever detail is in the JPG exactly; we don't attempt any restoration.
- Conversion runs on a temporary server-side copy that we delete right after.
Frequently asked questions
Can PNG recover quality lost in the JPG?
No. JPG compression is lossy and one-way — once detail is discarded during JPG encoding, no converter can bring it back. PNG only preserves what the JPG currently contains. If you have the original lossless source (camera RAW, PSD, TIFF), convert from there for true quality preservation.
How much bigger will the PNG be?
Typically 3-10x the size of the JPG source, though the exact ratio depends on image content. Photos with lots of fine detail or smooth gradients show larger relative growth than flat synthetic graphics.
Will the PNG have transparency automatically?
No — PNG supports transparency, but the output will be fully opaque unless you add an alpha channel in your editor afterward. Converting is the first step; masking or background removal is a separate editing task.
Does EXIF metadata transfer?
PNG doesn't have an EXIF block in the same way JPG does, but some EXIF is stored in PNG text chunks. Sharp's default conversion preserves recognized metadata where possible. For a metadata-free PNG, run the output through our /remove/png tool.
Is the PNG really lossless if the JPG was already compressed?
The PNG encoding step is lossless — it preserves every pixel the JPG decoded to. The existing JPG artifacts are baked in though, so the PNG faithfully captures an already-compressed image. 'Lossless from this point forward' is the honest framing.
