Need help?How to Convert JPEG to WebP Online
- Upload Your JPEG Files: Drag and drop or click "Add Files" to select JPEG, JPG, or JFIF images. Photos from cameras, phone exports, scans, and stock library downloads all work. Batch is supported — drop in an entire folder at once.
- Pick Quality Preset or Lossless Mode: Default is High (around 80% quality), the sweet spot for web delivery. Choose Highest / Very High / High / Medium / Low / Lowest, or set a custom Quality Percentage (1-100). Flip Lossless on (LOSSLESS_YES) when you need pixel-perfect output for screenshots, line art, or master assets — lossless WebP is still typically 25% smaller than the source JPEG.
- Resize and Set DPI (Optional): Pick a resolution preset (144p / 240p / 360p / 480p / 720p / 1080p / 1440p / 2160p / 4320p), enter custom width × height, or scale by percentage. Set DPI from 72 / 96 (screen) up to 300 / 600 / 1200 (print). You can also target an exact output file size in KB or MB and let auto-scale work backward.
- Convert and Download: Click Convert. Files process on our servers and download individually or as a single ZIP — no sign-up, no watermark, no sign-up.
Why Convert JPEG to WebP?
WebP is Google's modern image format designed specifically for the web. At equivalent visual quality, WebP files are 25-35% smaller than JPEG in lossy mode and around 26% smaller than PNG in lossless mode. Smaller images mean faster page loads, lower CDN bills, and better Core Web Vitals scores (LCP, in particular). Browser support is now ~96% globally — Chrome, Edge, Firefox, Safari 16+ (partial since 14), and Opera all render WebP natively.
- PageSpeed and Core Web Vitals wins — Google PageSpeed Insights and Lighthouse explicitly flag JPEG hero images with "Serve images in next-gen formats." Converting to WebP at 80% quality typically drops a 500 KB JPEG to 300-350 KB with no visible difference, directly improving Largest Contentful Paint scores.
- CDN and bandwidth savings — Sites serving millions of images (e-commerce catalogs, news, real estate listings) can cut image bandwidth by a third just by switching format. At Cloudflare or BunnyCDN egress rates, that's real money each month.
- Transparency without the PNG bloat — Need a transparent product photo or logo? Lossy WebP supports an alpha channel at a fraction of the file size of PNG. A 200 KB transparent PNG often becomes a 40 KB WebP.
- Shopify, WooCommerce, WordPress optimization — Most modern CMS platforms now serve WebP via
<picture>tags or auto-conversion plugins. Pre-converting your JPEG library means the platform doesn't have to convert on-the-fly (which costs CPU and storage). - Animated WebP as a GIF replacement — WebP supports animation at a fraction of GIF's file size with full 24-bit color. After this conversion, see GIF to WebP to migrate the rest of your motion assets.
- Archive of edited photos — When re-saving a JPEG generation-loses quality each time. Converting to WebP lossless freezes the current quality and lets you re-export to JPEG later without further degradation.
JPEG vs WebP — Format Comparison
| Property | JPEG | WebP |
|---|---|---|
| Compression type | Lossy (DCT, quantization) | Lossy (VP8) + Lossless (predictive coding) |
| Transparency | No | Yes (8-bit alpha) |
| Animation | No | Yes (animated WebP) |
| Typical file size (photo, same quality) | 1× baseline | 0.65-0.75× JPEG |
| Color depth | 8-bit per channel (24-bit RGB) | 8-bit per channel (24-bit RGB / 32-bit RGBA) |
| EXIF / ICC profile metadata | Yes | Yes |
| Browser support | Universal | All modern browsers (Chrome, Edge, Firefox, Safari 16+, Opera) (~96% global) |
| CMS / social uploads | Universal | Most platforms (some legacy systems still need fallback) |
| Best for | Universal photo distribution, email, print | Web delivery, hero images, product photos, transparency |
WebP Quality Quick Guide
| Preset | Approximate Quality % | When to use |
|---|---|---|
| Highest | 95-100 | Master assets, archival, lossless-adjacent |
| Very High | 90-94 | Print-quality web (fashion, photography portfolios) |
| High (default) | 78-85 | E-commerce, blogs, product photos — sweet spot |
| Medium | 65-75 | Thumbnails, listing tiles, lazy-loaded gallery items |
| Low | 50-60 | Placeholder / blur-up images, very small thumbnails |
| Lossless | n/a | Screenshots, UI captures, line art, transparent assets |
Frequently Asked Questions
What's the Difference Between JPEG and JPG?
Nothing — identical format. JPEG is the original standard name; JPG is a 3-letter file extension required by older Windows / DOS filesystems. JFIF is the most common JPEG file wrapper in use. XConvert handles all three identically. This page is the same as JPG to WebP.
Will converting JPEG to WebP improve image quality?
No — it cannot restore detail that JPEG compression already discarded. Both JPEG and lossy WebP are lossy, so transcoding is lossy-to-lossy. To minimize generation loss, set WebP quality to 85-95 (rather than the default 80) when re-encoding. If you have access to the original PNG or RAW source, converting from that instead of JPEG produces a noticeably cleaner WebP.
What WebP quality should I pick for a website?
80-85% (the High preset) is the long-standing recommendation from Google and matches what most CDN auto-conversion services use. For hero images and photography portfolios, push to 90%. For thumbnails and listing tiles, 65-75% is plenty. Inspecting the output in browser dev tools at the actual rendered size is the best way to confirm you're not over-compressing.
Will EXIF metadata, GPS, and ICC color profiles survive?
Yes by default. WebP supports EXIF, XMP, and ICC profile chunks and XConvert preserves them. If you want to strip EXIF for privacy before publishing (camera serial number, GPS coordinates), use the Remove Metadata option, or run Compress JPG first to clean before converting.
How much smaller will my WebP be vs the JPEG?
Typical real-world results: a 1920 × 1080 photo at JPEG 85 (around 450 KB) becomes 280-330 KB as WebP 85 — about 30% smaller. Photos with smooth gradients and skin tones compress especially well. Heavily textured images (foliage, gravel, fabric weaves) save less, around 15-20%. Lossless WebP averages around 26% smaller than the source PNG / lossless JPEG.
Does WebP work on iPhone, Safari, and email?
Yes for browsers — Safari has supported WebP since iOS 14 / macOS Big Sur (2020) with partial support, full from Safari 16. Browser coverage is now ~96% globally. Email clients are spottier — Gmail and Apple Mail render WebP, but some Outlook builds and older corporate clients don't. For email campaigns, keep a JPEG fallback or use WebP to JPG on the way back out.
Can I batch convert hundreds of JPEGs at once?
Yes — drop in entire photo folders, e-commerce catalog exports, or asset libraries. Each file converts in parallel withon our servers and downloads individually or as a single ZIP. Settings can apply uniformly to the batch or be overridden per file.
Should I use lossy or lossless WebP?
Lossy for photos and anything that started as JPEG (no benefit to lossless when the source is already lossy). Lossless for screenshots, UI captures, line art, logos, and master assets you'll re-export later. Lossless WebP averages around 26% smaller than PNG and 25% smaller than the equivalent lossless JPEG, so it's a strict upgrade for those use cases.
Can I go back to JPEG later?
Yes — see WebP to JPG for the reverse direction. Useful when uploading to a legacy CMS, email campaign, or print workflow that doesn't accept WebP.
