# Image Resizer/Rotator overview

Image Resizer/Rotator is a Quickbase Extension that resizes and rotates images stored in your Quickbase file attachment fields—or in Amazon S3—so photos uploaded from computers and phones end up a consistent size, file size, and orientation.

## What it can do

- **Resize to exact dimensions**—set a width and/or height in pixels. If you give only one, the other is calculated to keep the image's proportions.
- **Resize by a percentage**—shrink or enlarge each dimension by a percentage.
- **Resize to a target file size**—for example, make each image 250 KB or smaller.
- **Reduce file size by a percentage**—for example, make each image about half its current file size.
- **Rotate** images by 90, 180, or 270 degrees clockwise.
- Process **several images on one record** at once, or images across **many related records** with a query.
- Save the result back to the same field or to a **different file attachment field**, and record a checkbox, a date/time, and the before and after file size.
- Process images stored in **Amazon S3**.
- Run from a **button** on a Quickbase form, automatically in the **background (batch)**, or from **Quickbase Pipelines** and other API clients.

## Ways to run it

| **Method** | **How it starts** | **Best for** |
| --- | --- | --- |
| **Button** | A user clicks a formula button on a record. A small Image Resizer or Image Rotator window opens and shows the result. | On-demand processing of one record, or up to 50 related records. See [Resize images](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-resize-images) and [Rotate images](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-rotate-images). |
| **Batch** | A Quickbase email notification sends the processing arguments to the batch processor, which runs in the background. | Automatic processing (for example, when an image is uploaded) and jobs over 50 records. See [Batch processing](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-batch-processing). |
| **API** | Quickbase Pipelines or another client sends a request to the resize or rotate endpoint. | Workflows and integrations with no user present. See [API and Pipelines](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-api-and-pipelines). |

All three methods use the same parameters, described in [Formula URL parameters](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-formula-url-parameters).

## Supported file types

JPEG (*.jpg*, *.jpeg*, *.jfif*), PNG (*.png*), BMP (*.bmp*), GIF (*.gif*), TIFF (*.tiff*), PBM (*.pbm*), TGA (*.tga*), WebP (*.webp*), and QOI (*.qoi*). Files with any other extension are skipped with the message *Invalid File Extension - <ext> is not supported*.

> [!NOTE]
> Note
> 
> For now, TIFF images must use the *.tiff* extension. Files ending in *.tif* aren't accepted and show *Invalid File Extension - tif is not supported*. Rename the file to end in *.tiff* and upload it again.

- Images are turned to their correct orientation first (using the photo's orientation data), so results match how the image looks when viewed.
- Animated GIFs and multi-page TIFFs are reduced to their first frame or page.

## Limits

| **Limit** | **Value** |
| --- | --- |
| Size of a source image | 2 GB |
| Size of a processed image saved to a Quickbase file attachment field | 80 MB |
| Image dimensions | 20,000 pixels wide or high |
| Records per button or API request (multiple-record mode) | 50—use [batch processing](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-batch-processing) for more |
| Smallest target file size | 1 KB |

## Get started

1. **Authorize Image Resizer/Rotator for your app** with the installation wizard—see [Installation wizard overview](https://help.quickbase.com/quickbase-extensions/docs/en/juiced-add-on-installation-wizard-overview). For Image Resizer/Rotator the wizard only authorizes your app; it doesn't add fields or buttons. See [Finish and next steps](https://help.quickbase.com/quickbase-extensions/docs/en/finish-and-next-steps).
2. **Get your Client ID and server URL.** Every button formula needs your Client ID (*Q* followed by a number, for example *Q1234*) and your designated Image Resizer/Rotator server URL. [PLACEHOLDER: where to get your Client ID and server URL — revisit after the wizard setup for Image Resizer/Rotator ships]
3. **Add a button** that resizes or rotates images: [Resize images](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-resize-images) or [Rotate images](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-rotate-images).
4. Optionally, **track results** with extra fields—see [Track and store results](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-track-and-store-results).
5. **Fix problems.** If a button shows an error, or something doesn't work as expected, see [Image Resizer/Rotator messages and troubleshooting](https://help.quickbase.com/quickbase-extensions/docs/en/image-resizer-rotator-messages).
