Bulk image workflow
Process up to 20 images at once, download individual results or save everything as a ZIP.
Browser-based privacy
Everything runs in your browser. Images are never uploaded, stored, or sent to any server.
SEO-friendly filenames
Files download with clean, descriptive names ready for use on websites.
Simple controls, advanced options
Start with a single click, or use compression modes and resize presets for more control.

How It Works
Four simple steps — all in your browser

Convert to WebP in your browser

Privacy-First Compression
Your images stay on your device. Compression runs entirely in your browser using the Canvas API and WebP encoder, so files are not uploaded, stored, viewed, or sent to a server. Once you close the page, all image data is gone.

Need an Image Under 100KB?
Start with the 100KB compressor when an upload form, profile image, or website asset has a strict file-size limit. The tool runs in your browser and only enables downloads when the output reaches the selected target.
Open 100KB CompressorCompression Modes for Better Control
The single-image tool offers three compression modes to suit different needs. Balanced (the default) provides a sensible trade-off between file size and visual quality for most images. Best Quality prioritizes visual clarity, keeping dimensions and higher quality settings when the target size allows. Smallest File uses stronger compression and reduces dimensions earlier, which is useful when you need the smallest possible WebP file.
You can also enable the optional resize control to set a max width before compression — helpful when you have a large source image from a camera or design tool and want the output to fit a specific layout width. Presets include 1920px, 1600px, 1200px, and 800px, with a custom width option available too.

Frequently Asked Questions
What is 100KB Converter?▼
100KB Converter is a suite of browser-based tools for compressing and converting images. You can upload JPG, PNG, and WebP images, compress them under 100KB, and download them as WebP files — all without uploading anything to a server.
Are my images uploaded?▼
No. All compression and conversion runs inside your browser using the Canvas API. Your images stay on your device and are never uploaded, stored, or accessible by anyone else.
Why are downloads saved as WebP?▼
WebP typically produces files 25–35% smaller than JPG and PNG at similar visual quality. This reduces bandwidth, helps pages load faster, and makes images more efficient for websites.
Can every image be compressed under 100KB?▼
Most images can reach 100KB or less, but very large or highly detailed images may need dimension reduction. The tool tries to preserve original dimensions first, then reduces size if needed to meet the target.
Can I process multiple images at once?▼
Yes. The bulk image to WebP converter handles up to 20 images in a single batch, compresses each one to your chosen target size, and lets you download everything as a ZIP file with a CSV compression report.
Which image formats are supported?▼
You can upload JPG, JPEG, PNG, and WebP images. All downloads are WebP format. SVG, GIF, PDF, and other formats are not accepted.
Does this work on mobile?▼
Yes. The tool works in any modern mobile browser including Chrome, Safari, and Firefox. All processing happens on your device, so it works in offline-capable browsers too.
