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 JPG file, and keep your original: it is the only undo you have.
JPG Filters FAQ
Does the source format change how a filter looks?
+
It can. JPG stores 8-bit RGB through a lossy DCT with 4:2:0 chroma subsampling by default, so fine red text and hard edges are the first things to soften. Colour depth and the palette model in particular decide how smoothly a gradient or a blur can be represented.
Anything specific to JPG to keep in mind?
+
Yes — every save re-runs the quantiser, so repeatedly editing and resaving a JPG compounds generation loss even if you never lower the quality slider. That is often the difference between an effect looking clean and looking banded.
Can I undo a filter after downloading?
+
No — the effect is baked into the output pixels, which is the point of applying it. Keep the original file; that is your undo. Grayscale and blur in particular discard information that genuinely cannot be recovered.
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.
Can I run JPG Filters on several JPG images at once?
+
Yes. Drop the whole set into the upload area and they queue in parallel with identical settings — that is the main reason to do this in a browser rather than one file at a time in an editor. Free accounts run one file per batch; a pass lifts that.
What happens to EXIF and colour profile data?
+
Camera EXIF (ISO, shutter, lens, GPS) and the embedded ICC profile are carried across by default, because dropping the profile is what makes colours shift on re-import. Use the privacy option to strip metadata before download if you are about to publish the file.
Does JPG Filters cost anything?
+
No. JPG Filters is free with no account, no watermark on the output and no signup wall in front of the download. Uploads are deleted automatically a short time after the job finishes.
Is there a file size limit on JPG Filters?
+
Yes: free accounts process images up to 5 MB each, which covers essentially every camera JPG and phone photo; the work is done by libjpeg-turbo and libwebp, the same libraries a desktop editor links against. Larger files are the one thing the free tier will stop you on, and the limit is per file rather than per batch.
Why does a PNG site host JPG Filters?
+
PNG.to is built around the format you use when you cannot afford to lose a pixel: lossless, alpha-capable, and the correct answer for screenshots, logos, line art and anything with hard edges. Image work is rarely one step: people arrive to change a format and leave needing the picture a different size, a different weight or a different shape. Running JPG Filters on the same upload pipeline, the same size caps and the same account is the whole reason it is here rather than on a fourth tab.
What should I do with the result once JPG Filters is finished?
+
The converter on this site moves images to and from PNG, JPG, WebP, GIF and SVG — which is the step where the decision about transparency actually gets made. That is the step most people actually came for, and doing it after JPG Filters rather than before it means the conversion works from the file you finally settled on.
Is JPG Filters here the same tool the sibling sites run?
+
The engines are shared — the same libraries, the same workers, the same limits. What differs is the advice, and the advice here starts from one fact about the format this site is named after: there is no quality slider to get wrong — a PNG round-trips bit-exactly, so the only thing edits cost you is file size. A PNG site is opinionated about where PNG is the right destination and where it is not, and that judgement is worth more than the button.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, and nothing you process is indexed, listed or used for anything else. Free accounts exist for history and batch size, not for access.
