If you have tried to upload a TIFF file to WordPress or Shopify, you already know the problem: both platforms block TIFF uploads by default. TIFF is a print format — browsers cannot display it, and CMSs are built for web images. The fix is to convert your TIFF to WebP before uploading. WebP is natively supported by WordPress (since version 5.8) and Shopify, and it is the best-performing format for web delivery.
Why WordPress and Shopify Block TIFF Files
Both platforms restrict uploads to formats browsers can actually display: JPG, PNG, GIF, WebP, and SVG. TIFF is not a browser-displayable format — it is used for print production, archival photography, and design workflows. Uploading a TIFF would result in a broken image on the front end, so the platforms block it at the upload stage.
The correct workflow: keep your TIFF as your master file for print or archiving, convert a web copy to WebP for uploading to your CMS. WebP gives you the best balance of file size and visual quality for any web context.
Converting TIFF to WebP Before WordPress Upload
The straightforward workflow:
- Convert your TIFF to WebP using the free browser tool — no upload, no signup. Quality 85 is the right setting for most product, blog, or portfolio images.
- Download the WebP file — it is typically 85-99% smaller than the TIFF. A 40MB product photo becomes under 1MB.
- Upload directly to WordPress Media Library — WebP is natively accepted since WordPress 5.8. No plugin needed for upload.
- Use in your posts and pages as normal.
The result: images that load significantly faster, better Core Web Vitals scores (LCP in particular), and no need to run a separate image optimization plugin after upload. The conversion is done before the file hits WordPress.

Shopify natively supports WebP for product images and serves WebP to browsers that support it (essentially all modern browsers). The workflow for product photography:
- Receive high-res TIFF from your photographer or produce it in your design workflow.
- Convert to WebP at quality 85-90 using the free converter. Product images benefit from slightly higher quality (88-92) if they will be zoomed on the product page.
- Upload the WebP file to your Shopify product image gallery as normal.
Shopify also accepts JPG and PNG — but WebP produces the smallest files at equivalent visual quality, which means faster product page load times and better conversion rates. Page speed is a direct factor in Shopify store performance.
WebP vs Other Formats for CMS Uploads
| Format | WordPress | Shopify | File Size vs TIFF | Browser Support |
|---|---|---|---|---|
| WebP | Yes (5.8+) | Yes | 85-99% smaller | All modern browsers |
| JPG | Yes | Yes | 80-95% smaller | Universal |
| PNG | Yes | Yes | 40-70% smaller | Universal |
| AVIF | Yes (6.5+) | Partial | 90-99% smaller | Most modern browsers |
| TIFF | Blocked | Blocked | — | Not supported |
WebP is the best default choice for both platforms. It has near-universal browser support and delivers smaller files than JPG or PNG at the same visual quality.

Why won't WordPress let me upload a TIFF file?
WordPress blocks TIFF uploads because browsers cannot display TIFF images. Convert your TIFF to WebP (or JPG/PNG) first, then upload the converted file. WebP is the recommended format for best web performance.
Does Shopify support WebP images?
Yes. Shopify natively accepts WebP uploads and serves WebP to supported browsers. It is the best format for Shopify product images — smaller files than JPG or PNG at equivalent quality.
Do I need a WordPress plugin to use WebP images?
No. WordPress natively accepts WebP uploads since version 5.8 (released 2021). If you convert your TIFF to WebP before uploading, no plugin is needed. Just upload the .webp file to your Media Library.
What quality setting should I use for product images?
Quality 85-90 is the standard range. For product images that customers zoom on, use 88-92. For blog post images or thumbnails viewed at small sizes, quality 80-85 saves file size without visible degradation.
