JPG to WEBP
Compress JPG images as WebP – up to 30% smaller
Why JPG → WebP?
WebP is the modern standard for web images: smaller files, faster loading times, better SEO scores. Convert your JPGs directly in the browser, without uploading.
Frequently Asked Questions
What is the difference between JPG and WebP?
WebP offers better compression than JPG at the same or better visual quality. A WebP file is typically 25–35% smaller than an equivalent JPG.
Who benefits from converting to WebP?
WebP is especially beneficial for web developers and website owners, as smaller image files lead to faster loading times and better Core Web Vitals.
Can I adjust the WebP quality?
The converter uses a quality of 85%, which represents a good compromise between file size and visual quality.
Does WebP support animations?
Yes, WebP supports animations (Animated WebP). However, this converter only converts static JPG images to WebP.
About WebP
WebP was developed by Google in 2010 and is the only mainstream image format that offers both lossy and lossless compression in a single container. The lossy variant uses VP8 intra coding and typically achieves 25–35% smaller files than JPEG at the same subjective quality. The lossless variant is based on prediction and LZ77 compression and is about 26% smaller than PNG at identical pixel fidelity. WebP supports transparency with an alpha channel, animations, EXIF and XMP metadata, and color depths of up to 8 bits per channel. Safari did not support WebP until version 14 (2020), which slowed adoption for years; since 2021, however, the format is supported by all modern browsers. For web developers, WebP is the best choice when loading time and bandwidth are priorities, since a single image type covers both compression strategies. Google has recommended WebP as the standard web image format since 2019 and offers WebP 2 as an experimental further development, though it has not yet entered any standardization process.
About JPEG
JPEG (Joint Photographic Experts Group) was standardized as ISO 10918 in 1992 and remains the most widely used image format for photographs worldwide. Its lossy compression is based on the discrete cosine transform (DCT) and typically achieves compression ratios of 10:1 to 20:1 with barely perceptible quality loss. The algorithm was developed starting in 1986 by a working group led by Hiroshi Yasuda and quickly became the standard for web images, digital photography, and social media platforms. JPG files support 8-bit color channels in RGB color space and embedded EXIF metadata containing camera settings, GPS data, and timestamps. The format does not support transparency or animation and allows only one color space per image – limitations that are rarely relevant for its primary use as a photo format. With repeated compression, quality degrades progressively due to generation loss, making JPG unsuitable for editing and better suited as a final output format. The .jpg extension instead of .jpeg dates back to the 8.3 character limitation of early Windows file systems. JPEG XL was proposed as a successor in 2021 but has so far failed to gain meaningful market acceptance against WebP and AVIF.
Why convert JPG → WEBP?
JPG (JPEG) is the most widely used image format worldwide, supported by virtually every camera, browser, and image app. It uses lossy DCT compression that degrades quality with each save and doesn't support transparency. Converting to WEBP is required when you need lossless compression (PNG for screenshots/graphics), transparency support, or want to use a modern format with better compression like AVIF or WebP. For archiving and professional editing, WEBP is often the better choice since it produces no compression artifacts and maintains quality across repeated saves.
