Image to PNG

Convert images to PNG format with transparency support

About PNG Format

PNG (Portable Network Graphics) is a lossless image format that supports transparency. It's ideal for graphics, logos, and images that require a transparent background or need to maintain perfect quality.

Benefits of PNG

  • Lossless compression - no quality loss
  • Supports full transparency (alpha channel)
  • Perfect for logos, icons, and graphics
  • Universally supported by all browsers and devices

Convert a browser-readable image to PNG while keeping the pixels lossless. Transparent pixels stay transparent when the source format and browser provide an alpha channel; JPEG backgrounds remain solid.

What is an image to PNG converter?

This tool decodes a supported image in your browser and exports a new PNG file. PNG uses lossless encoding and can store transparency, but converting a JPEG cannot restore detail that was already lost.

When to convert an image to PNG

Transparent graphics

Use an existing transparent PNG or browser-supported WebP with alpha for logos, icons, and overlays.

Text and screenshots

PNG keeps sharp edges and small text without adding another lossy JPEG encode.

Lossless working copy

Keep the decoded pixels in a lossless PNG when you do not need a smaller photo file.

How image to PNG works

The browser reads the selected image, draws it to a canvas, and creates an image/png download. The conversion is local; the output contains the pixels the browser could decode, not a higher-resolution version of the original.

PNG compared with JPEG and WebP

PNGGraphics and transparencyLossless output; can include alpha transparency.
JPEGPhotographs and smaller filesLossy and cannot store transparency.
WebPModern web deliveryMay be lossy or lossless; browser support for decoding varies by format and device.

Local browser conversion

The conversion runs on your device with browser image APIs. Common JPEG, PNG, GIF, BMP, and WebP files usually work; HEIC, HEIF, and TIFF support depends on the browser and operating system decoder.

PNG conversion limits

The tool exports one still PNG image. It does not restore JPEG detail, preserve animation from an animated GIF, or guarantee that every HEIC, HEIF, or TIFF file can be decoded by your browser. PNG photos can also be larger than the source JPEG.

Frequently Asked Questions

Does converting JPEG to PNG improve quality?
No. PNG prevents additional loss after conversion, but it cannot recover JPEG artifacts or missing pixels.
Will a JPEG become transparent?
No. A JPEG has no alpha channel, so the exported PNG keeps a solid background.
Are my images uploaded?
The conversion is performed locally in your browser; the page does not need to upload the selected image.
