Introduction: Restaurants live and die by first impressions online. This Grubhub Image Optimization Guide for Restaurants explains why menu photos matter, what Grubhub requires, and practical steps—DIY and paid—to transform bland images into order-driving assets. Research shows that including photos in your Grubhub menu can increase item sales by up to 30%, and restaurants that follow menu best practices see as much as 70% more orders and 65% higher sales, according to Grubhub. Whether you manage a café, food truck, or full-service restaurant, this guide gives actionable shooting tips, a step-by-step upload workflow, troubleshooting for rejected images, and modern AI options to deliver compliant, high-converting photos fast.
Why food images matter for online orders
High-quality photos improve conversion, reduce ordering errors and speed decision-making. Multiple studies support this: Grubhub reports a 30% increase in menu item sales when photos are added, while Orders.co finds roughly 15% more orders when images are high quality. Another study summarized by FoodPix AI shows a typical 25% boost in menu conversion when images are used thoughtfully. Beyond immediate sales, photos build trust—90% of diners research a restaurant online before visiting, according to Grubhub—so strong visuals are marketing and customer service in one asset.
Good photos also reduce questions and incorrect orders. When customers see an accurate picture of portion size, plating and key ingredients, the number of special requests and mistakes drops. Grubhub also notes that adding images helps customers order faster and reduces errors, leading to happier customers and fewer refunds or negative reviews. That’s why investing time in menu photography pays off across operations and revenue.
Grubhub’s image requirements and best practices
Before shooting or uploading, follow Grubhub’s technical rules. Menu images must be square (1:1 aspect ratio), at least 200×200px, and in PNG format. Only actual food photos are accepted—no coupons, interior shots or generic stock images. Clean plating and neutral backgrounds maximize the food focus; Grubhub recommends images that go straight toward the food rather than busy styling. Meeting these technical specs prevents automatic rejections and speeds approval, which is critical when you want changes live quickly.
Best-practice checklist: crop to square, save as PNG, ensure the file is high-resolution but optimized for web, and keep the subject centered. If you need different crops for other platforms, export platform-specific versions; for cross-platform workflows see our cross-platform photo workflow and consult platform-specific guides like our Uber Eats Image Optimization Guide and DoorDash Photography page for nuances.
How do I upload and format food photos on Grubhub?
Uploading correctly avoids delays. Log into your Grubhub for Restaurants dashboard, open the Menu section, select the menu item and choose Add Photo. Prepare your image as a square PNG at or above 200×200px, named clearly so your team can manage files (example: "chicken-parmesan_12oz_v1.png"). In the item editor you can add a short description and confirm the photo displays correctly in the thumbnail. Save changes and wait for Grubhub’s moderation if required. If you have many items, batch-upload using the menu CSV import and attach images with the file names referenced in your import.
Step-by-step upload guide: 1) Edit photo to square PNG, 2) Use descriptive file names and keep a spreadsheet of images, 3) Open Menu > Item > Add Photo in your Grubhub dashboard, 4) Add alt-text and a clear description to help customers, 5) Save and verify live.

What are Grubhub’s technical requirements for menu images?
Direct answer: square 1:1 aspect ratio, minimum 200×200 pixels, saved as .png, and only real food photos. Grubhub explicitly disallows promotional images, logos-only pictures, or interior shots as item images. Those rules are strict because the platform wants consistent thumbnails and accurate depictions of dishes for customers. Keep backgrounds neutral and ensure color accuracy so customers receive what they expect, reducing complaints and returns.
Also consider alt-text and file naming for internal SEO and team organization. While Grubhub does not expose traditional SEO fields like a website, descriptive file names and concise item descriptions help customers and your staff. A name like "grilled-salmon-with-asparagus_1.png" is far more useful than "IMG_1234.png" for batch uploads and future edits.
DIY food photography tips for busy restaurants
You don’t need a studio to take menu-ready photos. Natural window light, a clean neutral plate, and simple composition make the difference. Shoot from three reliable angles—overhead flat-lay, 45° for bowls and burgers, and close-up for toppings or texture. Keep props minimal and avoid distracting tablecloths. Clean plating and a single garnish can dramatically improve perceived value. For practical staging, follow our guide How to Stage Food Like a Professional Stylist.
- Use window light and white reflector; avoid direct sunlight
- Stabilize your smartphone on a tripod or stack of books
- Shoot at the dish’s natural height—avoid extreme angles
- Edit minimally: exposure, white balance, crop to square and export PNG

Comparing professional photography vs AI-enhanced photos
A pro shoot delivers creative control, custom styling and brand-specific imagery; it’s ideal for hero shots and campaigns. However, it can be expensive and slow. AI-enhanced photos like those from YummyPic are cost-effective, fast and scale well for full menus. For many operators, the optimal approach blends both: hire a photographer for hero images and use AI to fill out the remainder of the menu quickly.
Cost example: a professional food photographer can charge per-image or a day rate, while AI services often cost a few dollars per image. Our pricing page covers options and credits for rapid image turnaround and shows how AI reduces per-image cost dramatically: see Pricing for details. If budget is tight, AI is a pragmatic way to capture the 30% potential sales uplift Grubhub reports without a full shoot.
Troubleshooting rejected photos and moderation tips
If Grubhub rejects an image, common reasons include non-food content, wrong file type, or improper aspect ratio. Immediately check the file format (must be PNG), confirm it’s square, and verify the content shows the actual dish. If the issue is moderation delay, contact Grubhub support and provide the item name and image file name. Keep a revision history and spreadsheet of uploads to quickly swap files if needed.
Include alt-text and a concise description when uploading to reduce ambiguity. If you run frequent promotions or seasonal items, pre-format those images and keep them ready for rapid swaps.
