Troubleshooting

Something not working as expected? Find the tool, find the symptom, and try the fix. Most problems have a quick answer.

Image Upscaler

The first upscale is very slow

Common causes

  • The AI model is downloaded and prepared on first use
  • The browser tab was switched away right after clicking

What to do

Wait for the first job to finish; later jobs are much faster. Stay on the tab for a second after clicking Upscale Image, because processing starts on the next screen refresh.

The success message doesn't mention AI (classic engine used)

Common causes

  • You're on a phone or tablet
  • The photo is larger than about 10 megapixels
  • WebGL isn't available in this browser

What to do

Use a desktop or laptop browser for small or old photos. Large photos rarely need upscaling; check the size you actually need first.

The result says it was auto-limited to fit your device memory

Common causes

  • The target size was more than your computer could hold in memory

What to do

Choose 2x instead of 4x, or crop the photo first so there are fewer pixels to enlarge.

Edges have bright halos or the photo looks plastic

Common causes

  • Sharpness set too high
  • Too much denoise without detail recovery

What to do

Reset all sliders to zero and run again. Add Denoise first for grainy photos, then a little Detail Recovery, and only then Sharpness.

The downloaded file is huge

Common causes

  • PNG was chosen for a photo

What to do

Download as WebP or JPG. If you need an exact size for a form, run the result through the image compressor.

Image Cropper

The crop is smaller than the form requires

Common causes

  • The original photo is small
  • The crop frame covers only a small part of the photo

What to do

Watch the Selection readout while cropping and make the frame larger. If the crop is still too small, enlarge it afterwards with the image upscaler.

My passport photo was rejected

Common causes

  • Head too small or too large in the frame
  • Wrong ratio for the country
  • Background or lighting problems

What to do

Check your country's size and head height in the passport photo size guide, use the matching preset or custom ratio, and retake the photo against a plain light wall if needed.

A transparent PNG got a white background

Common causes

  • It was exported as JPG

What to do

Choose PNG or WebP as the export format to keep transparency.

The photo appears sideways

Common causes

  • The photo was stored sideways with a rotation tag

What to do

Use the rotate buttons to turn it in 90-degree steps before cropping.

Image Compressor

The upload form still says the file is too big

Common causes

  • The form counts 1 KB as 1000 bytes
  • The form also limits pixel dimensions

What to do

Type a target a few KB below the limit (97 for a 100 KB limit). If the form also has a dimension limit, enter a width as well.

The compressed photo looks blurry or blocky

Common causes

  • The target is very small for a large, detailed photo

What to do

Enter a smaller width so the tool can keep a higher quality, or choose WebP, which looks better than JPG at the same size.

The file is too small for a minimum size

Common causes

  • Some forms require a minimum file size, for example 20 KB

What to do

Use Quality mode with a higher quality, or a larger width, until the estimate is above the minimum. The 20 KB guide covers this case.

A transparent background turned white

Common causes

  • JPG was chosen

What to do

Choose WebP or PNG to keep transparency.

Background Remover

The model download fails or stops

Common causes

  • Unstable connection
  • Browser storage is full or blocked
  • A network filter blocks huggingface.co or cdn.jsdelivr.net

What to do

Reload the page on a stable connection. Allow site data for this site, free up browser storage, or try another network.

It removed the wrong thing

Common causes

  • Something else in the photo is more eye-catching than the subject
  • The subject has low contrast against the background

What to do

Crop closer to the subject and run it again. In our tests, cropping fixed a case where bright leaves were kept and a grey cat was removed.

There's a light or dark fringe around the edges

Common causes

  • Edge pixels still carry a little of the old background colour

What to do

Place the cut-out on a background of similar brightness, or start from a photo taken against a lighter, contrasting background.

It's slow

Common causes

  • WebGPU isn't available, so the processor is used

What to do

Use a current version of Chrome or Edge on a computer, where WebGPU is usually available. On the processor, about ten seconds per photo is normal.

Metadata Remover

It says no metadata was found

Common causes

  • The photo was already cleaned, for example by a messaging app or social network
  • It's a screenshot or an image saved from a website

What to do

Nothing to remove. If you expected location data, check the original file from your camera roll instead of a shared copy.

The cleaned photo appears sideways

Common causes

  • Keep photo rotation was switched off

What to do

Run the original again with Keep photo rotation on.

Colours look slightly different

Common causes

  • Keep color profile was switched off

What to do

Run the original again with Keep color profile on.

Format not supported

Common causes

  • The file is HEIC, RAW or another format

What to do

Convert it to JPG first (on iPhone, sharing a photo usually converts it), then clean the JPG.

QR Generator

My QR code won't scan

Common causes

  • Low contrast or inverted colours
  • Printed too small
  • A logo covers too much of it

What to do

Use a dark code on a light background, print it at least 2 × 2 cm (larger for distant scanning), keep the quiet margin around it, and choose High error correction if you add a logo.

The Wi-Fi code doesn't connect

Common causes

  • Network name or password typed differently from the router
  • Wrong security type
  • The password changed

What to do

Copy the name and password exactly, choose WPA/WPA2 for almost all networks, test with your own phone, and make a new code whenever the password changes.

The printed code looks blurry

Common causes

  • A small PNG was enlarged for print

What to do

Download the SVG for printing, or the PNG at 2048 pixels.
