How this works in your browser
Both effects run on a canvas in your browser using its built-in filter pipeline, which is hardware-accelerated and therefore effectively instant even on large images. Sepia is a colour matrix operation: each pixel’s red, green and blue values are recombined by fixed weights that push the whole image toward a warm brown, which is why the result looks tonally unified rather than simply tinted. Blur is a Gaussian convolution, averaging each pixel with its neighbours weighted by distance, with the radius controlling how far that averaging reaches. Both write into the pixel data itself, so the exported file carries the effect permanently and your original stays untouched on disk.
Image Filters (Sepia/Blur) vs. traditional online converters
| Feature | Image Filters (Sepia/Blur) (in-browser) | Traditional online converters |

| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |

Frequently asked questions
Can I control the strength of the effect?
Yes, both sepia intensity and blur radius are adjustable.
Where is the black and white filter?
That is a separate tool, Black & White, since it is such a commonly requested single effect.
Can I combine sepia and blur together?
Apply one filter, download the result, then run it through the tool again with the other filter for a combined effect.
Is blur here enough to hide sensitive information?
Not reliably, and it is worth being direct about that. Blurring is a reversible-looking transformation: at low radii, text can often be recovered by someone who knows what they are doing. To genuinely conceal a name, address or account number, cover it with a solid block rather than blurring it.
Can I undo the filter afterwards?
Not from the exported file, since the effect is baked into the pixels. Keep your original and treat each export as a new version, which also lets you try different strengths without losing anything.
Why does blur make the image look softer overall?
Because the blur is applied across the whole frame rather than to a selected region. It is intended for a mood or depth effect, not for obscuring one part of an image.
Is my image uploaded anywhere?
No. Both filters are applied inside your browser tab.
