What does Pixelate Image do?
Pixelate Image is a free online tool that can apply pixelation/mosaic effect to image. The PNG result from Pixelate Image is a separate copy to inspect before you use it elsewhere. One possible use is owned imagery given a pixel-art style.
Pixelation scales an image down and then scales it up, producing block-like detail. The first percentage controls the small middle image, while the upscale percentage determines the enlargement from that middle size.
The defaults of 10 and 1000 roughly restore the original width and height, but other combinations can change the output size. It is useful for a visible effect.
Privacy requires an independent review because pixelation alone may leave people or content easy to spot. Pixelation reduces the picture and then enlarges it.
The two percentages control those two stages. The second value can change the final size as well as the block size.
This effect is not secure removal of private content. Check both the appearance and output dimensions before using the result.
Make an image look pixelated online: steps
Before using Pixelate Image, decide what the new copy must contain and where it will be used. Choose a downscale percentage and calculate the matching upscale if you want to retain roughly the original size. Review the upload area and all values required by the current Pixelate Image form.
Choose the source
Compare a block-style design at its final display size. For Pixelate Image, choose one source from your device. Keep a source copy for another attempt.
Review the form values
Pixel size (lower = more pixelated) controls a value used by Pixelate Image. The starting Pixel size (lower = more pixelated) value is 10.
Upscale back to (%) controls a value used by Pixelate Image. The starting Upscale back to (%) value is 1000.
Run the file task
Use Process Pixelate Image after checking the source and form values. Wait for the job to finish. An error means this attempt failed.
Save and check the output
Check output width and height, block size and whether any information you planned to obscure remains apparent. Store the output on your device. Name this copy separately from the original.
Pixel effect: uses for Pixelate Image
Pixelate Image can help with small previews tested for a block effect. It can also be used for non-sensitive examples prepared for a design exercise. The PNG result from Pixelate Image must suit the intended reading or editing step, so keep the source until that check is complete.
- Owned imagery given a pixel-art style.
- Small previews tested for a block effect.
- Non-sensitive examples prepared for a design exercise.
- Obscured copies assessed before an independent privacy review.
Formats and limits for Pixelate Image
The Pixelate Image form accepts the image formats in the table sources. Each Pixelate Image upload can be up to 300 MB, which equals 300 MiB. The allowed suffixes on the Pixelate Image page do not prove that a source has valid content inside it.
| Accepted formats | Maximum file size | Output |
|---|---|---|
| JPG, JPEG, PNG, WEBP | 300 MB per file (300 MiB upload limit) | PNG |
The effect is applied to the whole image and is not a certified anonymization method. It provides no manual region selector on this page.
Practical checks for Pixelate Image
Choose how large the blocks should look. Test the effect on a copy first. Keep the source for a different trial.
The first scale shrinks the whole picture. The next scale grows that small result. Both values affect the new width and height.
A value of 10 followed by 1000 aims at the old size. Other pairs can make a smaller or larger file. Check the actual size in your viewer.
View the result where it will appear. Small previews can hide the block pattern. A large view can make it much more obvious.
Do not assume the effect makes secrets safe. Look for readable words and other clues. Use a proper removal workflow if the source must be cleared for public use.
How this tool works
Pixelate Image uses ImageMagick to handle the source on the server. The Pixelate Image request uses your chosen input rather than any local editing project left on your device. Check the PNG contents produced by Pixelate Image before treating them as ready for another app or reader.
For Pixelate Image, your browser uploads the source to our file-processing server. This is a server task, not local editing.
Files are due for deletion within 1 hour. Cleanup runs during normal service operation. Keep a local download for future use.
