PNG vs JPG: when to convert
PNG uses lossless compression and supports transparency — ideal for screenshots, logos, icons, and graphics with sharp edges or text. JPG uses lossy compression optimized for photographs — it produces much smaller files but doesn't support transparency and can introduce artifacts around hard edges. Converting PNG to JPG makes sense when you need a smaller file for email, web upload, or platforms that require JPG. It doesn't make sense if your image has transparency (which will become white) or if you need pixel-perfect reproduction.
How the conversion works
OnlyFiles draws your PNG onto an HTML5 Canvas element in your browser, then exports it as a JPG using the Canvas API's toBlob method. The entire process runs locally — your image is never uploaded. The output quality is set high enough that the difference from the original is imperceptible for most images, while still achieving the file size reduction that makes JPG useful. A typical 5 MB PNG screenshot becomes a 200-500 KB JPG.
When to use this
- Reduce file size for uploading to social media or a website
- Convert screenshots to JPG for email attachments
- Meet file format requirements for job applications or forms
Frequently asked questions
How much smaller is JPG compared to PNG?
JPG files are typically 5-10x smaller than PNG files of the same image. A 5 MB PNG screenshot might become a 500 KB JPG. The tradeoff is that JPG uses lossy compression, so there's a very small quality reduction.
Will I lose transparency when converting PNG to JPG?
Yes. JPG doesn't support transparency. Transparent areas in your PNG will become white in the JPG. If you need transparency, keep the PNG or convert to WebP instead.
Is the conversion done locally or on a server?
Entirely in your browser. Your PNG file is never uploaded — the conversion uses your browser's built-in Canvas API, so it's instant and private.
