2Pick your effects — grayscale, sepia, invert, blur, sharpen, brightness, contrast and saturation — and set the strength of each.
3Apply them all in a single pass rather than running the tool repeatedly, which is what accumulates visible damage.
4Download the filtered Image file, and keep your original: it is the only undo you have.
Image Filters FAQ
Can I apply the same look to a whole set?
+
Yes. One filter configuration is applied across the batch, which is how you get a visually consistent gallery rather than a set of individually-tweaked images that almost match.
Which effects are available?
+
Grayscale, sepia, invert, blur, sharpen, and brightness, contrast and saturation adjustment. They can be combined, and combining them in one pass is better than running the tool repeatedly.
Does the source format change how a filter looks?
+
It can. this format is read and written by the same streaming pipeline as everything else we support. Colour depth and the palette model in particular decide how smoothly a gradient or a blur can be represented.
Anything specific to Image to keep in mind?
+
Yes — the pipeline reads the real format from the file header rather than the extension, so a mislabelled upload still works. That is often the difference between an effect looking clean and looking banded.
Will Image Filters lower the quality of my images?
+
That depends on what you brought. A lossless source (PNG, BMP, TIFF) round-trips exactly; a lossy one (JPG, WebP, GIF) is already the product of one quantisation pass and only re-encodes if the operation genuinely requires it.
Can I run Image Filters on several images at once?
+
Yes, and mixing formats in the batch is fine — settings are applied per file with the right decoder for each. Free accounts run one file at a time; a pass removes that.
What happens to metadata and transparency?
+
EXIF and the ICC colour profile are carried across wherever the target format supports them, and an alpha channel survives into any format that has one. Transparency is only flattened when the destination format has no way to represent it.
Does Image Filters cost anything?
+
No. Image Filters is free without an account and adds no watermark. Uploads are deleted from the workers shortly after the job completes.
Why does a WebM site host Image Filters?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Image Filters on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Image Filters is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Image Filters here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploaded video is deleted from the workers shortly after the job finishes, nothing is watched and nothing is indexed. Free accounts exist for history and batch size, not for access.
