Sometimes an image needs a quick stylistic touch — a vintage sepia tone, a moody black-and-white, a slight blur for backgrounds, or just a brightness boost. You don't need a $20/month editor for that.
The Image Filters tool applies one of seven popular effects to any uploaded image in one click.
Step-by-step: how to use Image Filters
- Open the tool. Visit ilovepdf.cyou/image-filters.
- Upload your image. Drag and drop a .jpg, .jpeg, .png or .webp file.
- Pick a filter. Choose from grayscale, sepia, blur, brightness boost, high contrast, sharpen, or invert colours.
- Process. The filter is applied to the image using the sharp imaging library.
- Download. Save the filtered image as
ILovePDF-image-filters.png.

Pro tips for the best results
1. Sharpen subtly
Sharpen on already sharp images can over-enhance — use only on slightly soft inputs.
2. Combine in sequence
Apply filters one at a time across multiple runs for layered effects.
3. Crop and resize first
Get the composition right with Crop Image and Image Resize before filtering.
4. Remove background after
Apply colour filters first, then run Background Remover for clean composites.
Frequently asked questions
Can I adjust filter strength?
Filters apply at preset intensities. Custom intensity sliders are on the roadmap.
Can I combine multiple filters?
Apply one at a time across multiple runs. Stacked filters in one pass are coming.
Will my image look pixellated?
No. Sharp's pipeline preserves quality through filter operations.
Does it work on transparent PNGs?
Yes. Transparency is preserved through colour-affecting filters.
