With Uploadcare, you can easily build custom image transformation workflows and automate most of image manipulation and optimization tasks. For example, you can set up a chain of actions for user-generated images that'll unify their look.
Сhange format, crop and resize images to fit any design and any screen on the fly. Adjust image colors, apply artistic filters, and enhance. You can use and stack transformations right in the image URL:
Every URL transformation generates a modified image version on the fly, while the original file stays intact. The transformed image version will be cached on CDN nodes to optimize delivery.
Without any image processing operation in the URL, CDN instructs browsers
to show images (
Content-Disposition: inline) and download other file types
Content-Disposition: attachment). Browsers may not show all image formats,
HEIC format. If you need to display an image,
add any image processing operation,
-/preview/ for instance.
Also, you can use Proxy to apply image transformations without explicitly uploading them:
- Resize & Crop
- Color adjustments
- Photo filters
- Blur & Sharpen
- Rotate & Flip
- Face detection
- Color recognition
- Object recognition
List of supported image formats:
Some formats have several variations, and we support the most popular ones. Contact sales if you require additional formats or variations.
This section describes the limits to consider when implementing Uploadcare Image processing.
When processing images, add at least one of the following operations via their respective URL directives:
The dimensions you specify for the last operation should not exceed 3000x3000
pixels. You can go up to 5000x5000 pixels by explicitly setting
your image format to JPEG,
You can extend the output max resolution up to 8192x8192, and up to 16384x16384 for JPEGs in trade-off for increased latency. Contact sales to learn more about this option.
Any image transformation CDN URL is valid with an SVG file. Most operations
don't affect the response SVG body, while geometric operations
scale_crop) change SVG attributes and work as expected.
SVGs uploaded before May 26, 2021 still have
is_image: false and adding
processing operations to them will result in error. Contact
support to batch process previously uploaded files.
We don’t provide on-the-fly image processing for images greater than 75 Mpx in resolution: those are tagged as non-image files and can only be delivered via CDN as-is. Adding processing operations to non-image files will result in an error.
When the only image transformation you want is rotating, consider using the
preview control without any arguments. When
you use any of the transformations, we automatically rotate images according to
their EXIF orientation.
Animated images are treated as static by the transformations engine, consider checking out our GIF to Video workflow optimized for animated images delivery.
If you migrate your files to Uploadcare from a DIY solution or another file management service (Filestack, Cloudinary, etc.), you need to copy files and map image processing operations. Use a Migro tool (GitHub) to copy files.
For an example of comparing Filestack image processing operations to Uploadcare operations, see Migrating images from Filestack.
