About Image Format Converter
Convert images between PNG, JPEG, WebP, and BMP formats instantly in your browser. No upload needed. Convert PNG to JPG to reduce file size, or JPG to PNG to preserve transparency. Uses the Canvas API for client-side conversion.
Different use cases call for different formats. JPEG is the best choice for photographs and images with gradients — it produces small files and is universally supported. PNG is ideal when you need transparency or when pixel accuracy matters, such as logos, icons, and screenshots. WebP is the modern web standard, combining small file sizes with support for transparency.
Common conversions: PNG to JPEG to reduce file size for sharing; JPEG to PNG to add a transparent background; any format to WebP for web performance; WebP to JPEG or PNG for compatibility with older software.
Everything runs locally in your browser. No server involved.

Comparisons
PNG vs JPEG vs WebP
PNG is lossless and supports transparency, making it right for logos, icons, and screenshots where pixel-perfect accuracy matters — but it produces larger files for photographs. JPEG uses lossy compression well-suited to photographs, producing much smaller files at the cost of some fine detail and no transparency support.
WebP combines the best of both: it supports transparency like PNG while achieving file sizes closer to (often smaller than) JPEG, and is now supported by every modern browser. For most new web projects, WebP is the best default; keep PNG or JPEG on hand for compatibility with older tools.
Frequently Asked Questions
Can I convert PNG to JPEG?
Yes — upload your PNG and select JPEG as the output format. Note that JPEG does not support transparency; any transparent areas in your PNG will become white.
Can I convert JPEG to PNG?
Yes — select PNG as the output format. The converted file will be larger than the JPEG since PNG is lossless, but it can hold transparency.
What is WebP and why use it?
WebP is a modern image format developed by Google. It produces files 25–35% smaller than JPEG and PNG at comparable visual quality, making it the best choice for web use. All modern browsers support WebP.
Does the conversion preserve transparency?
Transparency (alpha channel) is preserved when converting to PNG or WebP. Converting to JPEG replaces transparent areas with a white background because JPEG has no alpha channel.
Is there a file size limit?
No server-side limit — processing happens entirely in your browser. Very large images (above 20 megapixels) may be slow depending on your device.
Why is my converted PNG larger than the original JPEG?
JPEG uses lossy compression to achieve small file sizes. PNG is lossless and stores every pixel exactly, so PNG files are inherently larger than JPEG at the same dimensions. If file size matters, keep using JPEG or switch to WebP.
Can I convert a screenshot to WebP?
Yes — screenshots are usually PNG. Upload the PNG, select WebP as output, and download the result. WebP handles screenshots well and produces much smaller files.
Why won't my HEIC photo open on my Windows PC?
HEIC is Apple's default photo format on iPhones, but many Windows applications don't support it natively. Convert it to JPG here for universal compatibility with any device or software.
Will converting JPEG to PNG give me a transparent background?
No — converting formats doesn't add transparency where none existed. JPEG files have no transparency information to begin with, so a JPEG-to-PNG conversion just produces a lossless PNG with a solid background.
What format should I use for a logo?
PNG or WebP with transparency, since logos typically need to sit on different colored backgrounds without a visible box around them — JPEG's lack of transparency support makes it a poor choice for logos.
