Frequently asked questions
How does the Compress image tool work?
Upload a supported file (image), run the tool, and download the result (Optimized image). The page sends your upload through Uppy into a real Transloadit Assembly, so the result demonstrates the same processing platform available through the API.
What is the maximum file size?
Files can be up to 25 MB on this public utility. Production workflows can accept larger files, process batches, import directly from cloud storage, and create several outputs in parallel.
Are uploaded files stored permanently?
The public tool processes files temporarily. Do not upload sensitive material. A production workspace gives you control over authentication, storage destinations, and retention.
Can I automate Compress image with an API?
Yes. The same processing capability is available through reusable Transloadit Templates. Trigger it from Uppy, a backend SDK, an API request, or a Smart CDN URL, then send results to storage and services you control.
What other file tools are available?
Browse the Image tools category for related utilities. Each page runs a real upload and produces a downloadable result.
Automate “Compress image” in your product
The useful version of an image is rarely just one file. Create the crops, sizes, formats, and visual treatments each surface needs, then connect the outputs directly to storage and delivery.
Consistent presentation
Apply the same crop, dimensions, and visual treatment to every incoming image.
One source, many variants
Create thumbnails, social crops, and high-resolution output in parallel.
Faster experiences
Optimize delivery weight while retaining the quality your interface needs.
Composable edits
Combine enhancement, background handling, watermarking, and format conversion.
Content-aware logic
Use detected metadata to filter or branch before expensive processing runs.
Smart CDN variants
Deliver exact dimensions from the edge instead of storing every possible copy.
Serve Optimized image only when a screen requests it
Smart CDN combines a reusable Transloadit Template with URL parameters and global caching. The live example below changes to match this kind of media.
Choose the image layout
What changes at the edge
One source can fill a landscape hero, a square card, or a portrait feed slot. The URL asks for the layout and Smart CDN caches it.
Fetching this variant…A catalog image pipeline
Generate product cards, zoom images, and social crops from one source.
A visual design system
Enforce dimensions, quality, and branding on user-generated images.
A responsive media layer
Request the right dimensions from a URL and cache the result globally.
Process uploads, batches, and cloud files with one workflow
Move this same capability into your product: process customer uploads and cloud files, then route the results to storage, webhooks, and delivery.
