PNG converter

PNG sits at the lossless end of the image world: perfect fidelity and real transparency, paid for in bytes. The converters below move images into PNG when you need a dependable editing or archival target, and out of PNG when a screenshot or export is too heavy to mail, upload or serve.

What is PNG?

PNG (Portable Network Graphics) is a lossless image format from 1996. It compresses with DEFLATE, keeps every pixel exactly as authored, and supports a full 8-bit alpha channel for transparency. That makes it the default choice for screenshots, UI mockups, logos and anything with sharp edges or text. The tradeoff is size: photographs stored as PNG are often several times larger than a visually identical lossy file.

Common questions about PNG

What is a PNG file and when should I use it?
PNG is a lossless raster format with full transparency support. Because it never discards detail, it's ideal for screenshots, logos, icons, diagrams, and anything with sharp edges or text. The tradeoff is file size: for photographs, PNG files are usually much larger than a JPG or WebP, which is why photos are better stored as JPG.
Is PNG lossless? Will I lose quality saving as PNG?
PNG is fully lossless, so saving or converting an image to PNG never throws away pixel data. That makes it the safe target when you want an exact copy. Just remember that converting a lossy source like JPG to PNG can't restore detail the JPG already discarded; it preserves what's there, it doesn't add quality back.
What can I convert a PNG into with hushvert?
hushvert converts PNG to JPG, WebP, AVIF, JXL, PDF, and ICO. JPG or WebP shrink photos, AVIF and JXL push compression further, PDF wraps your images into a document (one page per image), and ICO builds a favicon. All of these run in your browser with no upload.
How do I convert a JPG, HEIC, or other image into PNG?
hushvert converts JPG, WebP, AVIF, HEIC, JXL, BMP, TIFF, PDF, and SVG into PNG, all client-side. This is handy when you need transparency or a lossless working copy. Every one of these conversions happens locally in your browser, so the source file is never uploaded.
How do I turn a PNG into a favicon (ICO)?
Drop your PNG into hushvert and convert to ICO. It resizes your image to the standard icon sizes and packs them into a single multi-size .ico favicon, entirely in your browser. A square source image works best so the icon isn't stretched. Nothing uploads during the conversion.
