File Upload Limits Explained for Shopify Merchants

Two different numbers matter when collecting customer file uploads, the maximum size of any single file, and the total storage available across all files over time, and confusing the two leads to surprises either at the point of upload or months into growing volume.

This guide is for merchants who want a clear understanding of file upload limits, per-file size and overall storage, before building a collection process around customer-supplied files.

Quick Answer

Yes, understanding the difference between per-file limits and total storage prevents surprises later. Hulk Form Builder supports individual files up to 100MB, covering most production-quality logos, artwork, and documents, with substantial overall storage capacity behind it, meaning the per-file limit is rarely the binding constraint for typical use, while storage capacity scales with your actual upload volume over time.

What This Involves

File upload limits for merchants involve two distinct numbers, the per-file size cap determining the largest single file a customer can submit, and the total storage capacity determining how much cumulative file data the store can hold, and both matter differently depending on whether your bottleneck is individual file size or overall volume.

Who Needs This

• Merchants planning to collect customer file uploads for the first time
• Stores whose current upload limits have caused rejected submissions
• Businesses evaluating whether an app's limits fit their file types
• Teams estimating storage needs as upload volume grows
• Anyone confused about the difference between file size and storage limits

Why It Matters for Your Business

• Rejected uploads at checkout frustrate customers and cost sales
• Confusing per-file limits with total storage leads to poor planning
• Production-quality files, especially print artwork, can be genuinely large
• Storage needs compound as upload volume grows over months and years
• Understanding both numbers upfront avoids a painful mid-growth surprise
• The right limits depend entirely on your specific file types and volume

File Upload Limits Explained for Shopify Merchants

Step 1

Start by understanding your actual file size needs.

• Check the typical size of your highest-resolution customer files
• Note any file types, video, layered artwork, that run unusually large
• Confirm whether 100MB per file comfortably covers your typical uploads

Step 2: Install and Configure Hulk Form Builder

Understand how Hulk Form Builder handles both limits.

• Confirm the 100MB per-file cap against your specific file types
• Understand the overall storage capacity supporting cumulative uploads
• Recognize that storage, not the per-file cap, is the long-term consideration

Step 3

Estimate your realistic total storage needs going forward.

• Estimate monthly upload volume and average file size
• Project storage growth over the coming year
• Confirm the platform's storage capacity comfortably exceeds that projection

Step 4

Test with your actual largest realistic files before launch.

• Upload your genuinely largest expected file type
• Confirm it processes and attaches correctly within the limit
• Check upload performance on a typical customer's internet connection

Step 5

Monitor storage usage as your upload volume grows.

• Track cumulative storage usage over time
• Revisit projections if upload volume grows faster than expected
• Address storage concerns proactively rather than reactively

Examples & Use Cases

Custom Signage Business (Signage)
Problem: The merchant assumed a low per-file limit would be a problem but had never actually measured their file sizes
Setup: Checked actual artwork file sizes against the 100MB limit and confirmed comfortable headroom
Result: No uploads were ever rejected, and the assumed limitation turned out not to be a real constraint

Growing Print-on-Demand Store (Printing)
Problem: Rapid growth in order volume raised questions about whether cumulative storage would become a bottleneck
Setup: Estimated monthly upload volume and projected storage needs against the platform's capacity
Result: Storage capacity comfortably exceeded projected growth, resolving the concern before it became a problem

Best Practices

• Distinguish clearly between per-file size limits and total storage capacity
• Check your actual largest file types against the per-file cap
• Estimate realistic monthly upload volume for storage planning
• Project storage growth over the coming year, not just today
• Test with genuinely large realistic files before launch
• Monitor cumulative storage usage as volume grows
• Address capacity concerns proactively rather than after hitting a limit

Summary

File upload limits involve two distinct considerations, per-file size and total storage capacity, and understanding both prevents surprises whether at the point of upload or months into growing volume. The core steps are checking your actual file sizes against the per-file cap, estimating realistic storage needs over time, and monitoring usage as volume grows.

Whatever your file size and volume needs, Hulk Form Builder supports uploads up to 100MB per file with storage capacity built to scale alongside you.
