UPLOADS

Elegant User Interfaces

Get started quickly with minimum configuration and improve the user experience of your application using one of the three File Picker implementations.

Different Upload Methods

Beyond the picker widgets, Filestack offers easy ways to get files uploaded and ready for delivery.

Efficient

Multipart Uploads lets you upload a large file in smaller, more manageable chunks. Individual pieces are then stitched together after all parts have been uploaded. The individual part uploads can even be done in parallel.

Content Ingestion Network Icon

Reliable Service Everywhere

Whether your users are on a high speed network or on a rural high latency network anywhere on the globe, Filestack’s Content Ingest Network enables transfer of files to the cloud.

Intelligent Ingestion Icon

Worry-Free

Ensure a 99.999% upload success rate using the Filestack Intelligent Ingestion.

Cloud Uploads

Cloud Upload-Ready

Upload files from your users’ cloud provider accounts.

Upload tags

Organized

Automate tagging uploaded files effortlessly. Use tags to group and classify your files.

Drag and Drop

With Filestack's Drag-and-Drop you can easily add drag and drop file uploading support to your website.

Custom Source

Customizable Integration

With Custom Source functionality you can add your own integration to the File Picker based either on a static list of files or dynamic integration of your choice.

Cloud Storage

Easy Cloud Storage Integration

By default, Filestack stores uploaded files to an internally managed S3 bucket. If you already have a cloud storage solution in place and would like to integrate it with Filestack, we allow that as well.

DELIVERY

CDN Icon

Optimized Content Delivery

To empower our users with CDN delivery, Filestack partners with Fastly CDN, one of the fastest and most secure content delivery networks. Every file that is uploaded through Filestack’s File Picker or RESTful API generates a CDN URL that delivers content at a blazing speed.

Cache Icon

Save Time with Caching

FileStack URLs are cached to ensure fast file delivery. The cached copy of any unique Filestack URL will live for 30 days – it will then be re-cached only when it is requested again.

Any Device Icon

Images for All Screens

Whether users have their images on their desktops, laptops, tablets or any other mobile devices – Filestack seamlessly integrates to provide a consistent crisp experience for the user.

File URL Customization

Personalize your file URL using the Custom CNAME feature. For example, when a user is looking to access a file, instead of seeing “cdn.filestack.com” they can see “cdn.fs.yourbusiness.com”.

Flexibility

Storage aliases are a premium feature that allows you to use Filestack transformations and other add-ons with files not uploaded through Filestack.

User-friendly Document Previews

Empower your users with an easy way to preview documents in the browser.

SECURITY

Security Policies

Keep Your Application Safe

Filestack is equipped with security policies to safeguard your applications.
The policy determines which actions are authorized, and the signature authenticates the policy.

Block Unauthorized Requests

Domain whitelists prevent File Picker from being embedded on unapproved websites.
Whitelisting works by blocking requests that don’t contain an approved domain in the “Origin” header.

INTELLIGENCE

Tag Images

Detect general features of uploaded images both synchronously and through the Workflows. Filestack has partnered with best in class platforms to provide quick analysis of images and return actionable insights.

Detect interesting areas of an image and assess its overall saliency. Get information, visual properties, and heatmap data of your image.

Keep Images Safe for Work

Emotions Behind Images

Emotions Behind Text

Convey Images to Words

As an intelligence service of Filestack platform, Image Captioning is able to describe your images and return captions synchronously or even through the Workflows.

Tag Videos

Uncover insights within your videos with Filestack Intelligence using state of the art machine learning to automatically organize videos, streamline processes, and make decisions about video data without the need for manual analysis.

Keep Videos Safe for Work

Video SFW helps in providing safe video content for your audience. You will be able to block videos that violates the workplace rules such as pornographic, violent or gory content.

Check Images for Copyright

Now detect images that are copyright protected. Upload a single image or millions of images, a single API call will display the copyright status of any image. This is especially useful for businesses that rely on user generated content and require their uploads to be free of copyrights.

Optical Character Recognition

OCR extracts text from images so you don’t have to. Whether you are transcribing old documents, or grabbing license plate numbers from security footage, Filestack OCR reliably extracts printed and handwritten data from your images.

Correct Document Properties

Detect your document in the image, transform it to fully fit the image, and pre-process it to reduce noise and distortion. As a result, the accuracy of the OCR engine in text extraction will be increased.

Detect Potential Threats

Scan every file upon upload for viruses and malicious programs no matter what their file type. Filestack’s virus detection capabilities support scanning every file from images and video files to PDF documents for a secure document upload every time.
