Use Image Converter to turn an AVIF image into PNG or JPG when your editor, upload form or sharing workflow expects another format. Choose the output according to whether you need transparency. Then check the downloaded image’s dimensions, background and appearance: conversion changes the file format, but it does not guarantee a smaller file or restore detail lost earlier.

Choose PNG or JPG for the result you need

PNG output can preserve alpha transparency when Background Color is set to Transparent. The default White setting fills transparent areas with white. Black fills them with black. Selecting PNG alone is therefore not enough to keep a transparent background on this page.

JPG output uses a solid background. Select White or Black according to the surface where the image will appear. If Transparent is selected for JPG, this converter still uses white because the JPG path does not export an alpha channel.

For an opaque photograph, JPG may suit the destination workflow. For a logo that must sit over another background, start with PNG and Transparent, then inspect the result over a contrasting color. A white preview alone cannot distinguish a white pixel from a transparent area displayed on white.

Work through a transparent AVIF-to-PNG example

The checked example was a generated 1200 × 600 AVIF with an opaque blue left half and a transparent right half. It gave a clear way to verify both resizing and alpha. Set:

Output Format: PNG
Quality: High (90)
Max Width: 800px
Background Color: Transparent

Convert the file and download the PNG. The checked example produced an 800 × 400 PNG. Its right-hand area retained alpha 0, confirming transparency in that sample. Repeating the export with White produced an opaque white right-hand area instead.

Compare the same AVIF as JPG

Choose JPG (JPEG), keep Max Width at 800px and select White. The same checked AVIF produced an 800 × 400 JPEG with opaque white pixels in the original transparent area. Choosing Black produced opaque black pixels there. These checks describe a controlled example, not exact color or byte guarantees for every input.

Resize without enlarging or stretching

Max Width offers Keep Original, 1920px, 1280px, 800px and 640px. A wider image is reduced proportionally. For a 1200 × 600 source, 800px gives 800 × 400: both dimensions use the same two-thirds scale.

A source already narrower than the chosen maximum stays at its original size. Selecting 1920px for an 800-pixel image does not upscale it. Keep Original retains the decoded dimensions rather than applying a width reduction. Check small text and fine edges after downsizing; details can become less readable even when the aspect ratio is correct.

Treat quality as an encoder setting

The values 70, 80, 90 and 100 are settings, not percentages of original quality. JPG, WebP and AVIF output use lossy encoding. Raising a setting cannot recover missing detail from an already compressed input.

PNG output on this page uses a limited-color palette of up to 256 colors. A colorful photograph, smooth gradient or soft edge can therefore look different after PNG conversion. A value of 100 is not a universal lossless guarantee. Inspect the areas that matter rather than assuming the maximum setting makes every source identical to the output.

GIF and default LZW TIFF output do not use the quality setting in the same way. This page is a format converter; it does not offer a target-byte-size control. If you need to resize or compress several still images as a group, use Batch Image Compressor and review its own settings and result report.

Check input limits and frame behavior

The default upload limit is 30 MiB, or 31,457,280 bytes, for one image. The upload area shows the active limit. An image above 100 million decoded pixels can be rejected even when its compressed file is smaller than the byte limit.

Supported input includes AVIF, JPG/JPEG, PNG, WebP, GIF, TIFF/TIF and SVG. SVG input becomes raster output. HEIC and PSD have separate HEIC Converter and PSD Converter pages.

PNG and JPG output use the first frame or page of the source. The page does not offer a frame or page selector. For a moving sequence, use an animation workflow rather than expecting one PNG or JPG to contain every frame.

Download and review the image

Images are uploaded to the server for conversion. After a successful conversion, the original is scheduled for deletion after about one minute and the generated download after about ten minutes. Cleanup runs periodically, so removal is not immediate. Save the output promptly.

Open it in the application that needs the new format. Check dimensions, alpha or background, color changes, small text and actual file size. Keep the AVIF original so you can make another export with different settings without relying on the temporary download.
