Category	Image File
Description	PNG images provide lossless compression, that is why the quality of the picture is nice, but the size of the file is huge. Because of it this file format is used by photographers. PNG may have several layers of transparency and even include short text descriptions which help search engines to examine the file. Although PNG was developed to replace GIF and partly other formats, it doesn’t support animation since it can’t contain several images like GIF.

WEBP File

File extension	.WEBP
Category	Image File
Description	WebP is a new lossy image file format, whose mission is to overthrow JPEG, which has long been the ruler of the web image world. Although it is not expected to outdo JEG in image quality right away, it seems to be outdoing it in user-friendliness. With Webp, you get a same-quality image almost 50% smaller than its JPEG counterpart. Webp uses VP8 ñ an open-source codec, and a RIFF-based container, which creates a good potential for further development. The format was created by Google.

We migrated our e-commerce product images from PNG to WebP and the average page weight dropped by about 40%. The converter processed our entire 1,500-image library in under ten minutes.

Our Google PageSpeed score was dragged down by large PNG images. Converting them to WebP was the recommended fix, and this tool made the bulk conversion simple enough that we could do it without developer involvement.

Running a photography portfolio site, I converted all PNG previews to WebP and load times improved measurably. The converter preserved transparency correctly, which matters for images with transparent borders.

PNG to WebP Converter — Frequently Asked Questions ▼

What is a PNG file?

PNG (Portable Network Graphics) is a lossless raster image format from 1996. It supports full alpha-channel transparency and produces relatively large files compared with modern compressed formats.

Why convert PNG to WebP?

Lossless WebP is roughly 25-35% smaller than PNG at identical visual quality. Lossy WebP can shrink photos by 70-90%. Smaller files mean faster page loads and better Core Web Vitals scores.

Does WebP preserve PNG transparency?

Yes. WebP supports a full 8-bit alpha channel, so transparent PNGs convert with their transparency intact — no loss of compositing fidelity.

Will quality drop after conversion?

Lossless WebP is mathematically identical to the source PNG. Default lossy WebP at quality 80 is visually identical for photos and far smaller. The online tool picks sensible defaults automatically.

Can every browser display WebP?

All current versions of Chrome, Edge, Firefox, Safari, and Opera support WebP. Only very old browsers (IE 11, Safari before macOS 11) cannot — a vanishingly small share of traffic.

What is the maximum file size?

The online converter accepts PNG files up to 50 MB. For larger images, use Total Image Converter on Windows.

Are my uploaded files kept private?

Uploaded files are deleted automatically after you download the WebP. They are not stored, indexed, or shared. Convert sensitive material locally with Total Image Converter.

Convert PNG to WEBP — Cut Page Weight Without Losing Quality

PNG gives lossless quality but heavy files. Converting PNG to WebP cuts file size by roughly 25–35% with lossless mode and far more with lossy mode, while keeping full alpha transparency. Every modern browser displays WebP natively. Drop your .png file above.

What Is PNG?

PNG (Portable Network Graphics) is the lossless raster format from 1996, designed as a patent-free replacement for GIF. PNG supports 8 and 16-bit channels, full alpha transparency, and Deflate compression. It is the universal lossless image format but tends to produce large files for photographic content.

What Is WebP?

WebP is Google's web image format from 2010. It supports both lossless and lossy compression, alpha transparency, and animation. Lossless WebP is roughly 25–35% smaller than PNG; lossy WebP can be 70–90% smaller for photos. Chrome, Edge, Firefox, Safari, and Opera all render WebP natively.
