Which filters can I apply to my image?
You can adjust brightness, contrast, saturation, hue, blur, sepia, grayscale and invert. Each filter has a slider so you can tweak the strength precisely instead of being stuck with a fixed preset. Multiple filters can be stacked together, for example a bit of extra contrast plus a slight blur. The preview updates in real time as you move the sliders, which makes it easy to dial in the exact look you want before exporting the final image.
Are filters applied destructively to my image?
No. The original image stays untouched in your browser. Filters are rendered on top of it using the canvas API, and only the exported file contains the baked in changes. That means you can keep adjusting sliders, reset everything to the defaults, or start over without losing your source picture. If you decide later to use a different look, just upload the original again and apply a new combination of filters.
Can I apply filters to a batch of images?
Yes. Drop multiple images onto the tool, set the filter values once, and the same configuration is applied to every picture. This is useful for creating a consistent look across a photo set, like a product gallery or a travel album. You can download each result individually or as a single ZIP. If you change the sliders the preview updates for the currently selected image, but exporting always uses the latest values for all uploaded files.
Do filters reduce the quality of my image?
Most filters are mathematical operations that do not introduce noise or compression artefacts on their own. Quality loss only happens when the result is saved as a lossy format like JPG. Choose PNG output if you want a perfectly sharp result, or JPG with quality 90 or higher if file size is more important. Stacking very strong filters such as heavy blur followed by sharpening can reduce detail, so use moderate values when you care about clarity.
Can I undo filter changes if I do not like the result?
Yes. Each slider has a reset button next to it, and there is a master reset that puts every filter back to zero. Because nothing is committed until you click export, you can experiment freely. There is also a before and after toggle that shows the original next to the filtered version, which is helpful when judging whether a change has actually improved the picture or made it look unnatural.
Does the filter tool work on my phone?
Yes. The interface is responsive, so sliders and the preview panel rearrange to fit narrow screens. All processing happens in the browser, so a recent phone handles small to medium images without trouble. Very large pictures may slow the live preview down, in which case lowering the preview resolution speeds things up while keeping the export at full quality. Touch gestures work for moving sliders and pinching to zoom into the preview.
