Convert JPG to PNG - Complete Guide

Converting JPG to PNG turns a raster image into a raster image. JPG 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 exactly what changes when you convert JPG to PNG, what is preserved, and when PNG is — or isn't — the right target format.

JPG to PNG for lossless quality and transparency

Use this JPG to PNG converter when a photo or graphic needs a lossless format for editing, transparent backgrounds, or crisp text and screenshots. PNG stores the image without lossy compression, so re-saving no longer adds new artifacts the way JPG does.

What JPG to PNG changes

• Produces a lossless PNG, so future edits and re-saves do not keep degrading the image the way repeated JPG saves do.
• Gives you a format that supports transparency, so you can later erase a background to a transparent alpha channel that JPG cannot hold.
• Keeps text, screenshots, logos, and sharp edges clean, since PNG avoids the blocky artifacts JPG adds around hard lines.
• Does not restore detail the original JPG already discarded; converting to PNG stops further loss but cannot rebuild lost quality.

Best results checklist

• Use PNG when you plan to edit the image repeatedly or need a transparent background later.
• Expect a larger file than the JPG, since lossless PNG stores more data; that is the trade for quality.
• For smaller web images that still beat JPG on size, convert to WebP instead of PNG.
• Start from the highest-quality JPG you have, because PNG cannot recover detail the JPG already lost.

Related JPG and PNG workflows

• JPG to WebP converter - Convert JPG to WebP for smaller web files that still support transparency.
• PNG to WebP converter - Turn the resulting PNG into a lighter WebP for faster-loading web pages.
• WebP to PNG converter - Convert WebP graphics into lossless PNG when an app rejects WebP.
• Image compressor - Reduce the PNG size for forms and uploads when the lossless file is too large.

What changes when you convert JPG to PNG

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

About the JPG format

JPG (JPEG) is the most widely used image format for photographs. Our free JPG converter allows you to convert JPG files to PNG, WEBP, PDF, GIF, and many other formats. You can also convert any image format to JPG for smaller file sizes and universal compatibility.

• Full name: Joint Photographic Experts Group
• Developer: JPEG Committee
• Introduced: 1992
• Compression: Lossy (DCT)
• Color depth: 24-bit (16 million colors)
• Opens with: every browser, every photo app, cameras

Where JPG is strong: small files that are ideal for photographs; supported by virtually every device and app; adjustable quality vs size.

Typical JPG 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 JPG 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 JPG to PNG

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