Tips

You can convert up to 50 JPG or PNG images simultaneously in one batch.
Compression uses a fixed 0.85 quality factor to reduce file size without visible visual degradation.
HEIC and RAW files are not supported natively by web browsers; export them to JPG before converting.

How to use it

1 Drag and drop up to 50 JPG or PNG images into the upload area or select them from your device.
2 Wait for the browser to process each image and review the original versus compressed file sizes in the list.
3 Download each converted WebP file individually or export all items together as a single ZIP archive.

What you should know

WebP is a modern image format developed to deliver smaller file sizes while preserving visual quality. Compared to standard JPEG encoding, WebP lossy compression typically reduces file size by 25 to 35 percent at equivalent fidelity, and produces substantially smaller files than PNG when converting transparent assets. Because online storefronts rely heavily on product photography, adopting WebP noticeably accelerates page render times and improves Core Web Vitals metrics. All major modern web browsers, including Chrome, Safari, Firefox, and Edge, support WebP decoding, making it the standard choice for web publishing and e-commerce platforms.

This tool encodes your JPG and PNG files into WebP using your browser's native canvas rendering engine. The conversion applies an 85 percent quality target (0.85 factor), striking a balance between low byte weight and crisp detail on retina screens. Alpha transparency in PNG files is retained during conversion. The canvas encoding process strips unnecessary EXIF metadata and color profile bloat, yielding clean web-ready files. You can queue up to 50 files per session. Because client-side browsers cannot decode HEIC or camera RAW formats directly, convert those files to standard JPG before processing them here.

Measured output sizes

Test files: a 4000×3000 landscape photo saved as a 1.61 MB JPEG, and a 1378×6047 full-page website screenshot saved as a 1.26 MB PNG. Run in Chrome 154 on a desktop PC; the photo took about a second per quality step, the screenshot about half a second.

Source file	Quality	WebP size	Change
Photo, 4000×3000	0.95	3.01 MB	+87%
Photo, 4000×3000	0.85	1.74 MB	+8%
Photo, 4000×3000	0.75	1.19 MB	−26%
Photo, 4000×3000	0.60	1.01 MB	−37%

Screenshot, 1378×6047	0.85	677 KB	−48%
Screenshot, 1378×6047	0.75	512 KB	−60%

The screenshot is where the conversion pays: 677 KB at the default quality of 0.85, against a 1.26 MB PNG, and 512 KB at 0.75.
A photo that is already a compressed JPEG has much less to give. At 0.85 it came out 1.74 MB, 8% above the 1.61 MB source, and only quality 0.75 and below produced a smaller file.
Quality 0.95 works against you on a photo: 3.01 MB, nearly double the original.
Each step below 0.75 returns less: the photo goes 1.19 MB, then 1.01 MB, then 784 KB, while the screenshot only moves from 512 KB to 373 KB across the same range.

Frequently asked questions

Do e-commerce platforms and online marketplaces support WebP images?

Independent store platforms like Shopify and WooCommerce fully support WebP product photos. However, regional third-party marketplaces such as Trendyol or Hepsiburada in Turkey, along with several legacy listing portals, often require traditional JPG or PNG uploads, so verify your sales channel requirements beforehand.

Will converting to WebP visibly reduce the quality of my product photos?

No. The converter uses an 0.85 quality factor, which eliminates redundant pixel data without creating perceptible compression artifacts or blurring fine product textures.

Are my images uploaded to an external server during conversion?

No. All decoding, compression, and WebP generation take place entirely within your browser using native web APIs, ensuring your media never leaves your device.
