Convert JPEG to PNG — Free & Private
Converting JPEG to PNG gives you a lossless copy of a compressed source — useful when you need to edit the image in layers without further degradation, add transparency, or bring it into a workflow that requires lossless input. The result is a pixel-exact copy of the JPEG's visible appearance in PNG format, ready for editing in Photoshop, GIMP, or Figma.

- 🆓 Free forever — no watermarks, no limits, no credit card
- ⚡ Instant conversion — uses browser Canvas API for real-time processing
JPEG vs PNG — Format Comparison
JPEG (JPEG (Joint Photographic Experts Group)) and PNG (Portable Network Graphics) use different compression and storage methods. The table below shows the key technical differences. JPG and JPEG are the same format — just different file extensions. PNG files are larger than JPG for photos but are pixel-perfect.

Key Questions About JPEG to PNG, Answered
Direct answers structured for AI extraction, voice search, and featured snippets.
Does converting JPEG to PNG improve the image quality?
No. Converting JPEG to PNG preserves the existing pixels exactly but cannot recover quality that JPEG's lossy compression already discarded. The pixels saved are the pixels they are — no detail is added back. What you gain is a lossless copy that will not degrade on future re-saves.
- JPEG compression permanently discards subtle detail — that data is gone
- PNG wraps the existing pixels in a lossless container — quality is frozen at current level
- Future edits and re-saves will not degrade quality further — that is the core benefit
- To get better quality, always start from the highest-resolution original source file
Why is the PNG so much larger than the original JPEG?
PNG is lossless — it stores every pixel's exact value. JPEG achieved its small size by permanently discarding subtle data. Converting JPEG to PNG restores none of that discarded data; it just wraps the existing pixels in a lossless container that takes significantly more space.
- A 300 KB JPEG photo typically becomes a 2–5 MB PNG
- PNG cannot use lossy compression, so it cannot match JPEG's file size for photos
- The size increase is expected and correct — it does not indicate a problem
- For web delivery, use WebP instead of PNG for photos — 25–35% smaller than JPEG with similar quality
Does PNG support transparency that I can use after converting from JPEG?
Converting JPEG to PNG gives you a PNG file that supports transparency, but the image itself has no transparent areas yet — the background is fully opaque. To add a transparent background, you need a background removal tool after the conversion. The PNG format then stores that transparency correctly.
- JPEG → PNG: creates a PNG container; the image has no transparency yet
- After conversion: use background removal to make areas transparent
- Then save as PNG again — the transparency is preserved in the lossless file
- Never save a transparent image as JPEG — all transparency becomes white
When should I convert JPEG to PNG instead of WebP?
Convert to PNG when you need a lossless working file for editing, when you need transparency, when a platform requires PNG format specifically, or when you're creating source assets for a design project. Convert to WebP when the goal is web delivery and file size matters — WebP is smaller than both JPEG and PNG.
- PNG: working files, editing, multi-save workflows, transparency, platform requirements
- WebP: web img tags, PageSpeed optimization, LCP improvement
- Keep JPEG: final web delivery when WebP is not feasible, email images, print
- Design rule: use PNG as source files, export JPEG or WebP for delivery
