You have a .webp file and need it as a JPEG. The right method depends on your device, whether you need to convert one file or dozens, and whether you have internet access. This guide covers five different methods — starting with the fastest option that works on every platform.
Method Comparison at a Glance
| Method | Platform | Batch | Quality Control | Internet | Best For |
|---|---|---|---|---|---|
| Online — ConvertIimage | Any device | 50 files | 90% slider | Required | Most users |
| Mac Preview | macOS | Multiple files | Quality slider | None needed | Mac offline |
| Windows Photos / Paint | Windows 10/11 | One at a time | Limited | None needed | Quick Windows fix |
| iPhone Safari save | iOS | One at a time | None | Required | 1–2 files on iPhone |
| XnConvert (Desktop) | Win/Mac/Linux | Unlimited | Quality slider | None needed | Large batches offline |
Method 1: Online Converter — Works on Any Device (Recommended)
Works on: Windows, macOS, iPhone/iPad, Android, Chromebook. Converts 1–50 files at once.
Go to convertiimage.com in Chrome, Safari, Firefox, or Edge. No account or software download required. The tool works identically on desktop and mobile.
Drag and drop your .webp files onto the upload zone, or click to open the file picker and select multiple files. You can upload up to 50 WebP files simultaneously. Wait for the progress bar to show all files loaded with green checkmarks.
From the output format dropdown, choose JPG. This applies to all uploaded files in the batch.
Adjust the quality slider to 90%. WebP is a more efficient format than JPEG, so converting to JPG at 90% quality produces files slightly larger than the WebP source but preserves all visible detail. Using the default (often 75–80%) degrades fine details — especially in photos with complex textures, gradients, or backgrounds.
Press Convert. A batch of 50 WebP files processes in 2–4 minutes. When done, click Download ZIP. Extract the archive — all JPEG files are ready, with original filenames and .jpg extensions.
Open 2–3 converted files in your target application — Windows Photo Viewer, Photoshop, your email client, or whatever was failing with WebP. Confirm the images display correctly and the quality is acceptable at 100% zoom.
Method 2: Mac Preview — Free Offline Conversion (macOS)
Using Mac Preview to Convert WebP to JPEG
- Open your WebP file in Preview — double-click the file, or right-click → Open With → Preview
- For multiple WebP files: select them all in Finder, right-click → Open With → Preview. All appear in the Preview sidebar
- In Preview, press Cmd+A to select all images in the sidebar
- Go to File → Export Selected Images
- In the export dialog, change Format to JPEG
- Drag the Quality slider to approximately 90% (roughly 90 on the 0–100 scale)
- Choose a destination folder and click Choose
Preview exports all selected WebP images as JPEGs in the chosen folder. Works completely offline, preserves original filenames, and handles multiple files efficiently. Fastest offline option on macOS.
Method 3: Windows Photos App or Paint (Windows 10/11)
Using Windows Photos App
Works for: Windows 11 and updated Windows 10 (Photos app version 2021+)
- Right-click your .webp file → Open With → Photos
- Once open in Photos, click the three-dot menu (⋯) at the top right
- Select Save as → choose JPEG from the file type dropdown
- Choose a save location and click Save
Limitation: One file at a time. For multiple files, the online method is far faster.
Using Microsoft Paint (Any Windows Version)
- Right-click the .webp file → Open With → Paint (if Paint can open WebP on your system — Windows 11 Paint supports it natively)
- In Paint, go to File → Save As → JPEG
- Choose save location and click Save
Method 4: iPhone — Convert WebP to JPEG on iOS
Using ConvertIimage in Safari (Recommended for iPhone)
- Open Safari on your iPhone and go to convertiimage.com
- Tap the upload zone and select your WebP file from your Photos library or Files app
- Set format to JPG and quality to 90%
- Tap Convert, then tap Download ZIP
- The ZIP file saves to your Files app → Downloads folder
- Open Files → Downloads → tap the ZIP to extract → your JPEG files are ready
Quick Single-File Method Using iOS Share Sheet
- Find the .webp image in your Files app or Photos
- Tap and hold the file → tap Share
- Scroll down and select Save to Photos — iOS sometimes converts WebP to JPEG during this step on older iOS versions
- Check your Photos app; if the saved image is now .jpg, you're done. If it's still .webp, use the ConvertIimage browser method above.
Method 5: Android — Convert WebP to JPEG on Android
Using ConvertIimage in Chrome (Recommended for Android)
- Open Chrome on your Android phone and go to convertiimage.com
- Tap the upload zone → select your WebP file from storage or Downloads
- Set format to JPG and quality to 90%
- Tap Convert, then Download ZIP
- The ZIP downloads to your Downloads folder — open it with a file manager app to extract the JPEG files
Note: Google Photos on Android supports WebP viewing — if you just need to view the file, open Google Photos and it renders WebP correctly. If you need a JPEG (for uploading, editing, or sharing with incompatible apps), conversion is necessary.
Method 6: XnConvert — Unlimited Offline Batch (Win/Mac/Linux)
For Large Batches (100+ Files)
- Download and install XnConvert (free, from xnview.com)
- Open XnConvert and click the + button or drag an entire folder of WebP files into the Input tab
- Go to the Output tab
- Set Format to JPEG
- Click the gear icon next to JPEG → set quality to 90
- Choose an output folder
- Click Convert — XnConvert processes 200+ files in under 30 seconds
XnConvert is the fastest offline solution for large WebP libraries. It's free, supports Windows, macOS, and Linux, and has no file limits. Ideal for photographers or designers with hundreds of downloaded WebP files to convert.
Quality Settings Quick Reference
| Purpose | JPG Quality | File Size vs WebP | Result |
|---|---|---|---|
| Print / archival | 93–96% | ~3× larger | Near-lossless from WebP |
| Email / sharing / uploading | 88–92% | ~1.5–2× larger | Indistinguishable from WebP |
| Web / social media | 82–88% | Similar to WebP | Excellent — very slightly softer |
| Thumbnails / previews | 75–82% | Smaller than WebP | Good at small sizes |

Frequently Asked Questions
The fastest method on Windows 10: open convertiimage.com in Chrome or Edge, upload your .webp files, set quality to 90%, and download the JPEG output — no software needed. For an offline method on Windows 10, use the Photos app (if updated to 2021 version or later) — open the WebP, click ⋯ menu, and save as JPEG. For bulk conversion, download the free XnConvert application which converts entire folders at once.
Yes — open Safari on your iPhone, go to convertiimage.com, upload your WebP file from your Files or Photos library, convert to JPG, and download the result. No app installation required. The converted JPEG saves to your Downloads folder in the Files app. This is the simplest no-app method for iOS users.
For 100+ files online: use ConvertIimage in two or more batches of 50 files each (free, no account needed). For offline bulk conversion on any OS: download the free XnConvert application — it processes entire folders of WebP files into JPEG with no file limits, completing 200 files in under 30 seconds on a modern computer. On Mac, Preview can also batch-export multiple WebP files: select all in the sidebar → File → Export Selected Images → JPEG.
Yes — macOS Preview has natively supported WebP since macOS Ventura (2022). On earlier macOS versions (Big Sur, Monterey), WebP support in Preview may vary — if Preview fails to open a .webp file on older macOS, use the online ConvertIimage method instead. On macOS Ventura and Sonoma, Preview opens and exports WebP files without any additional software or plugins.
Use 90% JPG quality as the default for WebP-to-JPEG conversion. WebP is more compression-efficient than JPEG, meaning a WebP file at equivalent perceptual quality is smaller than the JPEG — so converting to JPEG at the typical web setting of 82–85% will produce noticeable quality degradation compared to the WebP source. At 90%, the JPEG output is visually indistinguishable from the WebP original for most photographic content. Use 93–96% only for print or archival purposes where file size is not a concern.
At 90% JPG quality, the conversion loss is imperceptible for most photographic content — the human eye cannot detect the difference at normal screen viewing sizes. The only way to have zero quality loss would be to convert from the original uncompressed source to JPEG (since the WebP itself was already lossy-compressed). If preserving every pixel exactly is essential (for logos, screenshots, or working files), convert WebP to PNG instead — PNG is lossless and will store the WebP-decoded pixels perfectly, at a larger file size.
