Convert JPEG to PNG - Complete Guide

Converting JPEG to PNG stays in the raster image family but changes the traits that decide size, quality, transparency, editability, or device support. JPEG is a compressed image format widely used for photos, web graphics, email attachments, and social media uploads. PNG is a lossless image format commonly used for screenshots, transparent graphics, logos, and high-quality web images. Below is what actually changes in a JPEG→PNG conversion, what is preserved, and when PNG is the better choice than keeping JPEG.

What changes when you convert JPEG to PNG

• PNG is lossless, so no new compression artifacts are introduced. It cannot restore detail already discarded by JPEG, and the PNG file is usually noticeably larger.
• PNG supports transparency, but converting from JPEG does not add it — areas that were solid in the JPEG file stay solid.
• Expect a larger output file: PNG stores JPEG content with less aggressive compression.

About the JPEG format

JPEG is identical to JPG - both are the same image format. Our converter supports both extensions in the same browser workflow.

• Full name: Joint Photographic Experts Group
• Developer: JPEG Committee
• Introduced: 1992
• Compression: Lossy
• Opens with: every browser, every photo app, cameras

Where JPEG is strong: small files that are ideal for photographs; universally supported; adjustable quality vs size.

Typical JPEG uses: photographs, web and email images, social media uploads.

About the PNG format

PNG (Portable Network Graphics) is a lossless image format that supports transparency. Our free PNG converter allows you to convert PNG files to JPG, WEBP, GIF, BMP, PDF, and many other formats. You can also convert any image format to PNG to take advantage of its transparency and lossless compression.

• Full name: Portable Network Graphics
• Developer: PNG Development Group
• Introduced: 1996
• Compression: Lossless (DEFLATE)
• Color depth: 24-bit (16 million colors) + 8-bit alpha
• Opens with: every browser, Photoshop, GIMP, Figma

Where PNG is strong: lossless quality with no compression artifacts; full alpha transparency; crisp text, screenshots, and line art.

Typical PNG uses: screenshots, logos and UI graphics, images that need transparent backgrounds.

What PNG keeps

• Image dimensions (width and height in pixels) stay the same unless you resize.
• PNG adds: lossless quality with no compression artifacts.

Things to watch out for

• Converting JPEG to PNG will not improve quality beyond the source — choose PNG for compatibility or editing, not to "upscale" a compressed file.
• One PNG limitation to keep in mind: larger files than JPG for photographs.

When to convert JPEG to PNG

• Convert JPEG to PNG for screenshots.
• Convert JPEG to PNG for logos and UI graphics.
• Convert JPEG to PNG for images that need transparent backgrounds.
