How to Prevent Users From Uploading Too Large of Files
Merely a few years ago, uploading large files could sound like an unfunny joke from Reddit:
Now that networks have grown faster, nosotros don't sweat over progress confined and rarely delete information to free upward space. Just the problem with large files is still there, considering the sizes and the amounts of data we handle are growing exponentially.
Then, if you plan to enable large file uploads for your end users or arrange a cozy off-site backup storage, there are some sensitive points to consider.
How Large Is Big? A Large File Definition
In that location is a historical twist to this question. In the late 90s, when virtually PCs and workstations ran on 32-bit operating systems, large files were files that couldn't be handled because of a physical memory barrier equal to 2 GB. Though nosotros're now in the era of 64-bit computing, the 2 GB file upload restriction is still valid for some HTTP web servers and the bulk of browsers, except Google Chrome and Opera.
When it comes to other services, limits may significantly vary. For instance, twenty-25 MB is the maximum size for a Gmail zipper. If a file is bigger, the service automatically loads it to Google Bulldoze and offers to send a link. Fifty-fifty GitHub gives a warning if you desire to upload a file larger than l MB and blocks pushes that exceed 100 MB, offer an open up-source extension for large file storage (Git LFS).
Only let's come back to your job. If yous wanted to enable big file uploads on your platform, either for your cease users or for your team, you would probably expect for a cloud storage provider similar Google Cloud, Azure Blob, Dropbox, or Amazon S3.
The latter allows uploading objects up to 5 GB within a single functioning and files up to 5 TB if split into chunks and processed past the API. This is quite enough even to upload an astonishing 200+ GB Call Of Duty game file or all the seasons of The Simpsons in one go. 😅
At Uploadcare, we receive more 1 000 000 files every day from all over the globe, and consider files over x MB as large. Observing the trends, we can say that the size and the amount of media is growing by leaps and bounds, mainly thank you to the spread of video content.
Amid the largest files processed through Uploadcare in 2020 there are mp4 and quicktime videos (upwards to 84 GB), and zipped photograph archives.
Large File Uploading Issues and Possible Solutions
We grouped the challenges a developer can run into when enabling large file uploads into two categories: issues related to low speed and latency, and upload errors. Let's have a closer look at each of them and go over the possible solutions.
#1. Low upload speed and latency
The larger a file, the more than bandwidth and fourth dimension it takes to upload. This rule seems logical for a developer but can go a huge pain point for an end user.
"The biggest problem I came across was users wouldn't understand that it will have hours to upload a 5GB file"
~ @DiademBedfordshire on Reddit.
Speed problems usually occur if you transfer data in a single batch to your server. In this scenario, no matter where your end user is located, all the files go to a unmarried destination via the same road, creating gridlock like in Manhattan during rush hour.
And if the files are huge, your channel gets paralyzed: the speed goes down, and y'all can't apply your avails to their total potential.
Possible solutions: one) Prepare multiple upload streams. 2) Utilize a distributed storage network and upload files to the closest data center.
All this could result in a nightmare of an infrastructure, if it weren't for the major smart storage providers. At Uploadcare, we utilize Amazon S3, which receives numerous batches of information simultaneously and stores each of them in globally distributed edge locations. To increase the speed and latency even more than, we utilise an dispatch feature that enables fast transfers between a browser and an S3 bucket.
By adopting this method, y'all can produce a reverse CDN wow result: if a user is in Singapore, the uploaded data doesn't try to reach the main AWS server in the US, but goes to the nearest information eye, which is 73% faster.

#two. Uploading errors
The virtually common upload errors are due to limitations either on the user's browser or your web server.
We've already talked near browsers: 2 GB is a safe maximum supported by all browser types and versions. As for a web server, it can reject a asking:
- if it isn't sent within the allotted timeout menses;
- if memory usage limits are exceeded;
- if there's a network break;
- if the client's bandwidth is low or internet connexion is unstable.
Possible solutions: ane) Configure maximum upload file size and retentiveness limits for your server. two) Upload large files in chunks. iii) Employ resumable file uploads.
Chunking is the most commonly used method to avert errors and increment speed. By splitting a file into digestible parts, you overcome both browser and server limitations and can hands adopt resumability.
For case, Uploadcare's File Uploader splits all files larger than ten MB into five MB chunks. Each of these chunks is uploaded in 4 batches simultaneously. This method maximizes channel capacity usage, prevents upload errors, and boosts upload speed past upwards to 4x.
By performing multiple uploads instead of i, yous become more flexible. If a large file upload is suspended for whatever reason, yous can resume information technology from the missing chunks without having to showtime all once more. It's no wonder that major user-generated media platforms like Facebook and YouTube take already developed resumable API protocols: with such diverse audiences, this is the just way to deliver no matter the individual user context.
There are around 168 GitHub repositories for resumable file uploads, only over again, this method is already a office of major storage services similar Google Cloud and AWS, or SaaS file handling solutions. So there'due south no need to bother near forking and maintaining the code.
Ways to Enable Large File Uploads
As ever, in that location are three means to get: ane) Build large file treatment functionality from scratch. ii) Utilise open-code libraries and protocols. 3) Adopt SaaS solutions via low-code integrations.
If you lot choose to code yourself or utilize open-code solutions, you'll take to think nearly:
- Where to shop the uploaded files and how to accommodate backups;
- How to mitigate the risks of low upload speed and upload errors;
- How to deliver uploaded files if needed;
- How to balance the load if you use your servers for uploads and delivery.
When it comes to SaaS solutions similar Uploadcare, they take on the unabridged file handling process, from uploading and storing to delivery. On meridian of that:
- They use proven methods to upload and evangelize fast. And their job is to enhance your operation every day.
- They support a wide range of use cases and spare you from troubleshooting.
- They provide legal protection and compliance.
- They ease the load on your servers and your squad.
- They are maintenance free.
- They don't uglify your lawmaking.
Case report: Supervision Assist is an awarding that helps to manage practicum and internship university programs. In item, it allows university coordinators to supervise their students through live or recorded video sessions.
The company needed a secure HIPAA-compliant service that would handle large uncompressed files with recorded sessions in MP4, MOV, and other formats generated by cameras. The squad managed to build such a system from scratch, but somewhen got overwhelmed by upload errors, bugs, and overall maintenance.
"If an upload didn't complete, 1 of our devs would take to become look on the spider web server, see what data was stored and how much was there. Individually, information technology's not a big bargain, but over time that adds up."
~ Maximillian Schwanekamp, CTO
Past integrating Uploadcare, the visitor could seamlessly accept files of whatever format and as big as 5 TB without spending in-house evolution resources.
Apart from handling big file uploads, SaaS services can offer some additional perks like data validation, file pinch and transformations, and video encoding. The latter allows adjusting the quality, format and size of a video, cutting it into pieces, and generating thumbnails.
Wrapping Upward
There'south no universally accepted physical definition of a "large file," just every service or platform has its file treatment limits. Uploading big files without respecting those limits or the individual user's context may pb to timeouts, errors and low speed.
Several methods to face these bug include chunking, resumable uploads, and using distributed storage networks. They are successfully adopted by major smart storage providers and end-to-end SaaS services like Uploadcare, so you don't demand to build file handling infrastructure from scratch and bother nearly maintenance.
