How Each Feature Works
A closer look at the technology and benefits behind GetWebP's core capabilities
100% Local Processing & Privacy
GetWebP uses WebAssembly to run image codecs — including the official libwebp encoder — entirely inside your browser tab. No image data is ever sent to a remote server, logged, or stored. This architecture makes GetWebP fully GDPR-compliant by default: there is no data processor, no cloud storage, and no risk of third-party exposure.
Because processing happens on your own CPU, conversion speeds scale with your hardware and there are no server-side queue limits. A 50-image batch that would take minutes to upload, process, and download on a cloud tool completes locally in seconds.
This also means GetWebP works in air-gapped environments and restricted networks where uploading sensitive images to external services is prohibited.
- Zero data leaves your device — GDPR-compliant by design
- No file-size upload limits from the cloud
- Works in restricted or offline network environments
- Faster for large batches: no upload/download round-trip
WebP & AVIF Conversion
WebP is Google's open image format, supported by all modern browsers since 2020. Compared to JPEG, WebP reduces file size by 25–35% at equivalent visual quality for photographs, and up to 90% for graphics and illustrations that previously required PNG. GetWebP uses the reference libwebp encoder to ensure maximum compatibility and standard-compliant output.
AVIF (AV1 Image File Format) is the next step beyond WebP. Based on the AV1 video codec, AVIF achieves even greater compression — typically 20–50% smaller than WebP — especially for photographs. It is now supported in Chrome, Firefox, Safari, and Edge.
GetWebP lets you choose between WebP and AVIF, preview the output quality before committing, and adjust the quality slider to find the perfect balance between file size and fidelity.
- WebP: 25–90% smaller than PNG/JPEG, universally supported
- AVIF: 20–50% smaller than WebP for photos
- Live quality preview before export
- Lossless and lossy modes for both formats
Lossless & Lossy Compression Control
GetWebP exposes the full quality range of the WebP and AVIF encoders, from lossless (quality 100, bit-for-bit identical pixels) down to aggressive lossy compression for thumbnails and previews. The interactive quality slider shows a real-time before/after comparison so you can judge the visual impact before saving.
For most web use cases, a quality setting of 75–85 delivers files 60–80% smaller than the original JPEG or PNG with no perceptible quality difference on screen. For product photography where fine detail matters, lossless WebP gives you an exact pixel copy in a fraction of the PNG file size.
- Adjustable quality slider from lossless to maximum compression
- Real-time before/after comparison preview
- Typical 60–80% file-size reduction at quality 80
- Lossless mode for pixel-perfect output
Batch Image Processing
Rather than converting images one at a time, GetWebP lets you queue an entire folder of images and apply a single set of conversion settings across all of them. Free users can process up to 5 images per session; Pro users have no limit.
Each image in the batch is processed in a separate Web Worker thread, keeping the main browser thread responsive. Progress is shown per-file, and the final output is packaged into a single ZIP download so you can replace an entire image directory in one step.
- Process hundreds of images in a single session (Pro)
- Parallel processing with Web Workers — UI stays responsive
- Consistent quality settings applied across the entire batch
- One-click ZIP download of all converted files
SEO-Friendly File Renaming
Search engines use image filenames as a ranking signal for Google Images. A file named IMG_4021.jpg tells the crawler nothing; my-handmade-leather-wallet.webp tells it exactly what the image shows and matches the queries people actually type.
GetWebP's SEO rename feature lets you set a base keyword, and the tool automatically slugifies it — lowercased, hyphen-separated, stripped of special characters — to produce clean, crawler-friendly filenames. In a batch, each file is numbered sequentially (e.g. handmade-leather-wallet-1.webp, -2.webp) so the output is immediately ready for upload without manual renaming.
- Keyword-based filename slugification in one click
- Sequential numbering for batch exports
- Improves Google Images visibility for product and blog images
- Removes special characters and spaces that break some CDNs
Offline Capability
GetWebP is a Progressive Web App (PWA) that caches all required assets on first visit. After that, you can convert images with no internet connection at all — useful on flights, in fieldwork, or in secure environments where network access is restricted.
Because all image codecs run in WebAssembly locally, offline mode is fully featured: there is nothing that requires a server call. The extension version works offline by default since it runs entirely in the browser extension context.
- Full feature availability with zero internet connection
- PWA caching — works after first visit with no install required
- Ideal for travel, fieldwork, or secure offline environments
- Extension version is always offline-capable by default
Frequently Asked Questions
Everything you need to know about GetWebP's features and how it works
No. GetWebP processes all images directly in your browser using WebAssembly. Your files never leave your device, are never sent to any server, and are never stored anywhere online. This makes GetWebP suitable for confidential images, personal photos, and use in regulated industries where data residency matters.
GetWebP accepts PNG, JPG/JPEG, HEIC, HEIF, GIF, BMP, TIFF, and WebP as input formats. You can convert any of these to WebP or AVIF output. The extension also intercepts images on web pages, letting you right-click any image in your browser and convert it immediately.
Results vary by image content, but typical reductions are 60–90% for PNG graphics and 25–50% for JPEG photographs when converting to WebP at quality 80. Converting to AVIF can reduce files a further 20–50% compared to WebP. The live quality preview lets you find the smallest file size that still meets your quality standard before you export.
Yes. GetWebP is a Progressive Web App (PWA) that caches all assets on first load. After that, you can open it and convert images with no network connection. The Chrome extension version is always offline-capable because it runs entirely within the browser extension context.
Both are next-generation image formats recommended by Google Lighthouse, but AVIF (based on the AV1 codec) generally achieves 20–50% better compression than WebP for photographic content. WebP has broader compatibility and is supported in all modern browsers since 2020. AVIF has excellent support in Chrome, Firefox, Safari 16+, and Edge. For most web projects, WebP is the safe default; AVIF is the better choice when maximum compression is the priority and you can verify your audience's browser versions.
Yes. Drag and drop a folder or multi-select files to queue a batch. Free users can convert up to 5 images per session; Pro users have unlimited batch size. All images in the batch are processed in parallel using Web Workers, and the results are bundled into a single ZIP file for one-click download.
GetWebP has a free tier that includes local WebP conversion, batch processing up to 5 images, and offline capability. The Pro plan unlocks unlimited batch size, SEO-friendly file renaming, automatic EXIF removal, advanced quality controls, and priority support. You can try the web version at no cost without creating an account.
EXIF stripping is available on the Pro plan. EXIF metadata can contain GPS coordinates, device model, capture time, and other sensitive information. Removing it before publishing images on the web is a best practice for both privacy and file size — EXIF data can add tens of kilobytes to each image.
