Shopify store owners use OnlineTools4Free to optimize product images, compress PDF invoices, and generate social sharing images. No app installs needed.
A step-by-step workflow tailored for Shopify users. No installations, no accounts — just open the tool and go.
Compress and resize product photos before uploading to Shopify. Shopify recommends images at 2048x2048 pixels — use the Image Resizer to hit that target, then compress to keep file sizes under 200KB.
Shopify serves WebP images automatically when the browser supports it, but uploading pre-optimized WebP files gives you more control over quality. Use our JPG to WebP converter.
Use the OG Image Generator to create eye-catching images for when customers share your product links on Facebook, Twitter, or Pinterest.
If you send PDF invoices, size guides, or product manuals, compress them first with our PDF Compressor to keep email attachments small and downloads fast.
Create QR codes linking to product pages for use on packaging, flyers, or in-store displays. Our QR Code Generator supports custom colors and logo embedding.
Use the Collage Maker to create lifestyle collages showing multiple product angles or variations in a single image for your storefront or social media.
These tools are the most useful for Shopify users. All free, all browser-based.
No account, no plugins, no setup. Open the tool, process your file, use the result in Shopify.
