Image Upscaler
Increase image dimensions up to 4x or set custom output sizes. Ideal when you need larger images for print, slides, or better on-screen display.
Processing
The upscale runs server-side with Sharp and Lanczos3 resampling so larger exports stay smoother than a simple browser stretch.
Input formats
JPEG, PNG, and WebP images up to 20 MB
Output
PNG output for PNG inputs, JPEG output for other supported inputs
Best for
Print drafts, presentations, profile assets, and low-resolution images that need a cleaner larger export

Max input size: 20MB
How it works
- 1Upload your image (JPEG, PNG, or WebP up to 20MB)
- 2Choose a scale preset (1.5×, 2×, 3×, 4×) or enter custom pixel dimensions
- 3Output dimensions are shown as a live preview before you process
- 4Server uses Lanczos3 resampling for sharp, high-quality upscaling
- 5Preview before/after side-by-side, then download
About This Tool
Not every project starts with a high-resolution source file. Sometimes you only have a small asset and need a larger copy that holds up better in a presentation, on a print draft, or in a wider layout.
This page enlarges images using a high-quality resampling approach instead of a crude nearest-neighbor stretch. It is a practical option when you want a sharper larger export without adding design software to the workflow.
Why People Use It
- Preset scaling values from 1.5x to 4x
- Custom width and height controls for exact outputs
- Preserves PNG output for PNG uploads when transparency matters
Typical Use Cases
- Making small graphics usable in presentations or pitch decks
- Preparing larger copies of profile and marketing images
- Generating bigger image assets for print proofs
- Improving display size for web and CMS uploads
How To Use Image Upscaler
Step 1
Upload a JPEG, PNG, or WebP image.
Step 2
Choose a preset scale or enter custom output dimensions.
Step 3
Generate the enlarged image using the upscale engine.
Step 4
Download the new image and use it in your design or upload workflow.
Common Questions
Is this an AI generative upscaler?
No. The page uses high-quality Lanczos3 resampling for cleaner enlargement rather than a generative model that invents new content.
How much can I enlarge an image?
You can use preset scale values up to 4x or enter custom dimensions, subject to the page maximum output limits.
Will transparency be preserved?
Yes for PNG inputs. PNG files stay PNG so transparency can be maintained in the output.
