Convert JPG, WEBP, GIF, or BMP to PNG — free, instant, runs in your browser.
PNG uses lossless DEFLATE compression, meaning every re-save produces an identical pixel grid — unlike JPEG, which re-encodes and degrades slightly each time you hit Save. That makes PNG the right choice for logos, UI screenshots, line art, and diagrams: any image with sharp edges or flat blocks of color where JPEG's DCT compression would smear boundaries or introduce visible ringing artifacts.
The tradeoff is file size. PNG is almost always larger than JPEG for photographs, because DEFLATE is optimized for repetitive patterns (flat colors, text, gradients) rather than high-frequency photographic detail. A 1200×800 photo that compresses to 200 KB as JPEG might produce a 1.2 MB PNG. For photos destined for a website or email, JPEG or WebP is the better format — PNG's advantages only appear when you need pixel-exact fidelity or transparency.
Converting any other format to PNG is a one-way lossless step: the output PNG locks in whatever quality the source had, with no new compression artifacts added. PNG also supports a full 32-bit alpha channel, which JPEG, 24-bit BMP, and 1-bit GIF cannot match — making PNG the universal archival format for UI assets, icons, and anything with a transparent background.

What is a PNG file?
PNG (Portable Network Graphics) uses lossless compression, meaning no quality is lost when saving. Unlike JPG, PNG supports transparent backgrounds — essential for logos, overlays, and layered graphics. Use PNG when you need crisp edges or transparency; use JPG for photos where file size matters more.
Frequently asked questions
Can I convert a JPG to PNG without losing quality?▾
Yes. Converting JPG to PNG is lossless in this direction — the PNG preserves every pixel from the JPG. Any compression artifacts already in the JPG are preserved, but no new quality is lost.
How do I make a PNG with a transparent background?▾
Upload your image, then use our Watermark Remover to erase the background area. PNG supports an alpha channel for transparency, which JPG cannot.
Is it safe to convert images online with ToolChop?▾
Yes — all conversion runs directly in your browser using JavaScript. Your images are never uploaded to our servers, stored, or shared. You can verify this in your browser's Network tab.
What file formats can I convert to PNG?▾
ToolChop supports JPG, JPEG, WEBP, GIF, BMP, and TIFF as input formats. All convert to standard PNG output.
Is there a file size limit?▾
Since processing happens entirely in your browser, the only limit is your device's memory. Most images up to 50MB convert without issues.
How do I resize my PNG after converting?▾
Use the image resizer to scale to exact pixel dimensions. For social media or AI model inputs (512×512, 1024×1024), the resizer has preset sizes built in.
How do I convert PNG back to JPG?▾
Use the PNG to JPG converter. Converting back to JPG reduces file size significantly — ideal when you need to share photos by email or upload to platforms that prefer smaller files.
