Image Converter
Convert your images between popular formats like JPG, PNG, and WEBP directly in your browser. There are no uploads to a server, no quality-loss surprises, and no watermarks — just fast, private conversion that finishes the moment you drop a file.
Overview
Whether you need a transparent PNG for a logo, a lightweight WEBP for your website, or a universally compatible JPG for sharing, the Appzo image converter handles the round trip in a single click. Everything runs locally using your browser's native image engine, so even large files convert in seconds and your originals never leave your device.
What this tool does
The image converter re-encodes your photo or graphic from one format to another — JPG, PNG, or WEBP — using your browser's built-in canvas engine. You choose the target format and, for lossy formats, a quality level; the tool decodes the original, redraws it, and exports a brand-new file you can download instantly.
Problems it solves
- An app or website only accepts a format your image isn't in (for example, it rejects WEBP).
- A PNG screenshot is needlessly large and would be far smaller as JPG or WEBP.
- You need a transparent PNG but your source is a flattened JPG.
- You want to standardize a folder of mixed-format images into one consistent type.
Key benefits
- Convert to JPG, PNG, or WEBP in one click
- 100% client-side — your files never leave your device
- Preserve quality with adjustable output settings
- No watermarks, no sign-up, no file limits beyond 20 MB
Who it's for
How to use it
- 1
Upload your image
Drag and drop a JPG, PNG, or WEBP file into the upload area, or click to browse. Your file is loaded straight into the browser — nothing is sent to a server.
- 2
Choose the output format
Pick JPG, PNG, or WEBP as your target format. PNG keeps transparency and is lossless; JPG and WEBP are smaller and ideal for photos and the web.
- 3
Adjust quality (optional)
For JPG and WEBP, drag the quality slider to balance file size against visual clarity. PNG ignores quality because it is lossless.
- 4
Download the converted file
Preview the result with the before/after comparison, confirm the new file size, and click Download to save your converted image.
Example input and output
Example input
A 2.4 MB PNG screenshot of a dashboard (1920×1080) downloaded from a design tool.
Example output
A 320 KB WEBP file at the same 1920×1080 resolution and ~85% quality.
Converting the screenshot from PNG to WEBP cut the file size by roughly 87% with no visible difference, making it ideal for embedding on a fast-loading web page.
JPG vs PNG vs WEBP
Not sure which format to pick? Here is how the three formats this tool supports stack up.
| Feature | JPG | PNG | WEBP |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes (alpha) | Yes (alpha) |
| Animation | No | No | Yes |
| Typical file size | Small | Large | Smallest — about 25–35% under JPG |
| Best for | Photographs | Logos, graphics, screenshots | Almost anything on the web |
| Browser support | Universal | Universal | All modern browsers |
Short version: reach for WEBP on the web, PNG when you need transparency or crisp graphics, and JPG when you want a photo that opens everywhere.
Common use cases
Make images web-ready
Convert heavy PNG or JPG assets to WEBP to shrink page weight and improve Core Web Vitals without sacrificing visible quality.
Fix compatibility issues
Turn WEBP downloads into JPG or PNG so they open in older apps, editors, and content management systems that don't support WEBP.
Create transparent graphics
Convert to PNG when you need an alpha channel for logos, icons, and overlays that must sit cleanly on any background.
Standardize a library
Normalize a mix of formats into a single consistent type before importing them into a catalog, deck, or design system.
Tips & best practices
Pick the format that matches the job
Use PNG for graphics, logos, and anything needing transparency; JPG for photographs you want small; and WEBP when you want the best balance of quality and size for the web.
Mind transparency when going to JPG
JPG can't store transparency, so transparent areas become white. If your image relies on a see-through background, convert to PNG or WEBP instead.
Convert, then compress for the web
For the smallest possible web image, convert to WEBP and run it through the compressor — you'll often shave another 20–40% with no visible difference.
