Can I convert PNG to JPG online for free?

Yes. Drop your PNG, select JPEG as the output format, adjust quality to 85–90% and click Convert. The conversion runs entirely in your browser — no file is uploaded anywhere.

Does converting PNG to JPG lose quality?

Converting from lossless PNG to lossy JPEG introduces slight compression artefacts. Use a quality setting of 85–95% to keep the difference invisible to the human eye. The file will be significantly smaller.

What is the difference between WebP and PNG?

WebP is 25–35% smaller than JPEG and up to 80% smaller than PNG for equivalent quality. WebP supports transparency (like PNG). All modern browsers support WebP. PNG remains the right choice for maximum lossless fidelity or when sharing images outside web browsers.

Will converting to JPG remove the transparent background?

Yes — JPEG does not support transparency. Transparent pixels will be filled with the background colour you select (white by default). Use PNG or WebP if you need to keep the transparent background.

What quality setting should I use for web images?

85–90% is the standard recommendation for web use. At this setting, compression artefacts are invisible but file size is 50–70% smaller than lossless. For images where pixel accuracy matters (medical, print-prep), use 95%+ or PNG.

Does this tool upload my images to a server?

No. The entire conversion runs in your browser using the HTML5 Canvas API. Your images never leave your device and nothing is stored or transmitted.

PNG vs JPEG vs WebP — Which Format to Use?

Choosing the right image format affects file size, visual quality and browser compatibility. The three most common web formats each serve a different purpose:

Format	Compression	Transparency	Best For
PNG	Lossless	Yes (alpha channel)	Logos, screenshots, UI graphics, images with sharp edges or text
JPEG	Lossy	No	Photographs, complex scenes, product images where file size matters
WebP	Lossy or lossless	Yes	All web images — best compression, replaces both PNG and JPG online
GIF	Lossless (indexed)	1-bit (on/off)	Simple animations, limited to 256 colours
BMP	Uncompressed	No	Rarely used on web — legacy Windows format, very large files

When to Convert to WebP

WebP is the recommended format for most web images today. Google developed it specifically for the web. Key advantages:

25–35% smaller than JPEG at the same perceptual quality — directly improves page load time and Core Web Vitals scores.
Up to 80% smaller than PNG for lossless compression — dramatically reduces the size of large transparent graphics.
Supports transparency — unlike JPEG, WebP can have an alpha channel, making it a complete replacement for PNG.
Supported by all modern browsers — Chrome, Firefox, Safari (since 14), Edge and Opera all support WebP. Only IE11 and very old Safari versions do not.
Recommended by Google for Lighthouse and PageSpeed Insights — pages that serve WebP instead of JPEG/PNG typically see better performance scores.

When to Convert PNG to JPEG

PNG to JPEG is the right conversion for photographs that were accidentally saved as PNG. A photograph at PNG can be 5–10× larger than the same image as JPEG at 85% quality with no visible difference. Convert PNG to JPEG when: the image is a photo (not a graphic), transparency is not needed, and file size matters more than perfect pixel accuracy.

The Quality Slider — How It Works

The quality slider (10–100%) controls the compression level for JPEG and WebP output. A setting of 85–90% is the sweet spot: the file size reduction is significant but compression artefacts are invisible at normal viewing distances. Going below 70% introduces visible blurring around high-contrast edges. For lossless PNG output, the quality slider has no effect — PNG is always lossless.

Converting Images With Transparency

PNG and WebP support full alpha channel transparency. JPEG does not. When you convert a PNG or WebP with a transparent background to JPEG, this tool fills the transparent areas with the background colour you choose (white by default). If you need to preserve transparency, keep the output format as PNG or WebP.
