About This Tool
Different image formats serve different purposes. PNG uses lossless compression and supports transparency, making it ideal for logos, icons, and screenshots. JPG uses lossy compression that dramatically reduces file size for photographs by discarding visual detail the human eye barely notices. WebP, developed by Google, offers both lossy and lossless compression with better file sizes than JPG and PNG. BMP is an uncompressed format used in legacy Windows applications. This converter transforms images between these formats entirely in your browser using the Canvas API — no files are ever uploaded to a server. Your image never leaves your device.
Frequently Asked Questions
Are my images uploaded to a server?
No. All image conversion happens locally in your browser using the Canvas API. Your images never leave your device.
What file formats are supported?
You can convert between PNG, JPG (JPEG), WebP, and BMP formats.
Is there a file size limit?
No hard limit. However, very large images may take longer to process depending on your device’s memory and processing power.
Which format should I use for web images?
For photographs, use WebP (best compression) or JPG (widest compatibility). For images with transparency, text, or sharp edges (logos, screenshots, icons), use PNG or WebP. WebP supports both lossy and lossless compression and is supported by all modern browsers.
Does converting between formats affect quality?
Converting from a lossy format (JPG) to another lossy format (WebP) involves re-encoding, which can reduce quality slightly. Converting from lossless (PNG) to lossy (JPG) discards some data permanently. Converting from lossy to lossless (JPG to PNG) preserves the current quality but cannot recover lost detail. For best results, always work from the highest quality original.
