Photo Calorie Counter.
One photo. Full calories and macros in ~3 seconds. Free.
Snap your first meal free — foodidentifier.comA photo calorie counter estimates calories and macros from a picture of your food — no typing, no searching databases. Snap the meal at foodidentifier.com and get calories, protein, carbs, fat, fiber and sugar in about 3 seconds, free with no app or sign-up.
How it works — 3 steps
Photograph your plate
Open foodidentifier.com and tap the camera. Snap a clear photo of your meal from above — the whole plate in frame.
AI identifies food + portions
The model identifies each food item and estimates portion sizes against a 663-food database built from USDA and published nutrition data.
Calories, macros & spike score in ~3s
In about three seconds you get calories, protein, carbs, fat, fiber, sugar and a 1–100 blood-sugar spike score — plus an automatic diary entry.
Photo vs typing — why manual logging fails
Typing every meal takes 3–5 minutes and most people quit within two weeks. A photo takes 3 seconds and the diary builds itself.
What every scan gives you
Calories
Total calories for the meal, estimated from identified foods and portions.
Protein
Grams of protein — the macro most people under-track when logging manually.
Carbs
Total carbohydrates, including the breakdown that drives blood-sugar response.
Fat
Total fat, including the contribution from oils, dressings and cooking methods.
Fiber
Fiber grams — key for satiety and blood-sugar stability.
Sugar
Total sugar, so you can spot hidden sugars in sauces and drinks.
1–100 Spike Score
A blood-sugar impact score from 1 to 100 — higher means a bigger expected glucose spike.
Diary Entry
The scan saves automatically to your food diary so you can revisit it later.
How accurate is photo calorie counting?
Photo calorie counting is excellent for daily awareness, spotting patterns and building a consistent food diary without the friction of manual logging. Every estimate is grounded in a 663-food database built from USDA and published nutrition data.
For clinical precision — medical diets, research, or exact macro targets — weigh your food on a scale. Photo estimation gets you close; weighing gets you exact.

Scans great
- Single-plate meals (protein + veg + starch) — the scanner excels at clear, well-lit plates.
- Restaurant entrées — snap the plate when it arrives; no need to know the recipe.
- Homemade bowls — grain bowls, salads and stir-fries with distinct components.
- Snacks and fruit — a banana, handful of nuts or a protein bar scan in seconds.
Tricky — with a tip
- Mixed casseroles and one-pot bakes — the ingredients blend together. Tip: photograph before mixing, or note the main ingredients.
- Dark restaurants — low light reduces accuracy. Tip: move the plate near a window or use your phone flash.
- Layered dishes (lasagna, burritos) — portions per layer are hard to see. Tip: cut open and photograph the cross-section.
- Shared plates — the scanner estimates the whole plate. Tip: photograph your portion separately.

Photo calorie counter FAQ
Is this photo calorie counter really free?
Yes. You get one free photo scan per day at foodidentifier.com with no app download, no account, and no credit card. The scan returns calories, protein, carbs, fat, fiber, sugar and a 1–100 spike score.
How accurate is a photo calorie counter?
Photo estimation is excellent for daily awareness and tracking trends. It is grounded in a 663-food database and identifies portions from the image. For clinical precision (medical diets, research), weigh the food on a scale. See our accuracy guide for details.
Do I need to download an app?
No. FoodIdentifier runs entirely in your browser on iPhone, Android, desktop or tablet. Open the page, tap the camera, and photograph your meal. See how the app works for more.
Does it work on restaurant food?
Yes. The photo scanner identifies restaurant meals, mixed dishes and casseroles. For full menu decoding, use the restaurant decoder tool which breaks down an entire menu.
What about packaged food with a barcode?
For packaged products, use the barcode scanner instead of the photo scanner. It reads the barcode and pulls the nutrition label directly.
What macros does every scan show?
Each scan returns calories, protein, carbs, fat, fiber, sugar, a 1–100 spike score (blood-sugar impact), and an automatic diary entry you can revisit later.
Are my food photos private?
Photos are processed to return nutrition results and are not shared publicly. You do not need an account to scan, so there is no profile tied to your images.
How is this different from Cal AI?
Cal AI is a paid subscription app that was acquired by MyFitnessPal in March 2026. FoodIdentifier offers one free daily photo scan in the browser with no app, no account and no trial that converts. See the full Cal AI comparison.
