# Supported File Formats

Whether you shoot RAW or JPEG, Fotello’s got you covered.

Upload straight from your camera. Skip conversions and exports.

### Supported formats

* **RAW:** We support all RAW formats (ARW, NEF, CR3, and many more).
* **JPEG:** Standard `.jpg` / `.jpeg`.

If it imports and shows previews on your computer, it should upload to Fotello without any issues.

### Best practices

These settings prevent upload issues and missing previews.

* **Shoot uncompressed / standard RAW** or use **high-quality JPEGs**.
* **Avoid “high efficiency” modes** like **HEIF/HEVC** when shooting stills.
* **Avoid vendor-specific compressed RAW modes** if you see errors or broken previews.

{% hint style="warning" %}
Some “efficiency” and compression settings create proprietary files.

Those can fail to upload or preview correctly.

If you run into problems, switch back to **standard RAW** or **standard JPEG**.
{% endhint %}

#### Double-check settings before you shoot

A quick glance at your camera menu saves hours later.

Also avoid shooting **RAW + JPEG** for the same scenes.

Mixed formats can break bracket grouping.

### RAW vs. JPEG

Both work. Pick the one that matches the job.

#### RAW

RAW gives maximum dynamic range and detail.

That gives our AI more room to work.

Use it for tricky lighting like window pulls and dark corners.

#### JPEG

JPEG uploads faster and stays lightweight.

Use it for speed, on-site delivery, and same-day turnarounds.

{% hint style="info" %}
**Want to test both?**

Shoot the same scene in RAW and JPEG. Upload both to Fotello and compare results.

If you’re using a listing just for testing a few photos in both formats, message us in chat so we can credit you for it.
{% endhint %}

{% hint style="success" %}
Fotello always outputs photos in JPEG format, regardless of the input file type. These can be downloaded in web, print and full resolution. This ensures seamless compatibility with web and MLS platforms worldwide.
{% endhint %}

If thumbnails are missing, your files can still edit.
