Jewelry AI
Which image files the app accepts, and why a photo can be refused
The accepted image formats are JPEG, PNG and WebP. Whether your file is one of them is decided on your device, before an upload begins, from the type the photo picker reports. A refusal at this point is a fact about the file, not a verdict on the photograph.
The accepted image formats
Jewelry AI accepts JPEG, PNG and WebP. That is the whole list, and it is the same list wherever you enter the app with a photograph of your own.
The list, and the ceiling a source file has to stay under, are set out on the background remover page. This page does not restate that boundary or put a figure on it; it covers the other half of the question — where the accepting happens, and what the app is actually reading when it decides.
Everything below follows from one thing: the decision is made on your device, before an upload begins, on the type your photo picker reports.
Where the acceptance decision is made
Four facts explain nearly every refusal people meet when they pick a file.
- On the device, not after a trip to a server.
- The file is inspected where it already is. When the type is outside the accepted list, no upload starts for that file at all.
- Before the upload begins, not partway through it.
- You learn the answer at the moment of choosing, rather than waiting to find out that a file was never usable.
- From the type the picker reports.
- When you choose an image, the picker states what it is. That statement is what gets compared against JPEG, PNG and WebP.
- Not from the file name.
- The extension is a label attached to the name. Changing it does not change what the picker reports, so it does not change the outcome.
What the check reads and what it ignores
The gate uses one signal. Knowing which one removes most of the guesswork after a refusal.
| Signal | Used to decide? | Why |
|---|---|---|
| Type reported by the photo picker | Yes | This is the value compared against the accepted list of JPEG, PNG and WebP. |
| File name extension | No | Renaming a file does not change what the picker reports about it. |
| How the photograph looks | No | The gate compares types. Focus, lighting and framing play no part in this particular decision. |
| Which tool in the app you opened | No | The accepted list is the same list wherever you bring in a photograph of your own. |
Getting a refused photo into an accepted format
Five steps, in order, from a file that was refused to one that will be taken.
Read the refusal as a statement about the file
It tells you the type reported for that image was not on the accepted list. It does not tell you anything about how the piece was photographed, so leave the lighting and the setup alone for now.
Find out what the photo is saved as
Open the image in your gallery or file browser and look at the format it is stored in, not the name it was given. On a phone this is usually shown in the image details.
Export a copy in JPEG, PNG or WebP
Do this from the original image, using whatever export or convert option your gallery, camera app or editor offers. Keep the original as well, so you can go back to it if the copy loses something.
Check the copy is not a screenshot of the original
A screenshot is a picture of a screen, and it carries the detail the screen was showing rather than the detail the camera captured. For jewellery that difference lands exactly where it hurts: stones, engraving and links.
Pick the copy in the app
If the copy is one of the accepted types, the picker reports it as such and the app takes it. If it is still refused, the exported copy did not land in an accepted format, and the export step is the one to repeat.
Quick check before you pick a file
Four things worth confirming while the file is still on your device.
- Confirm what the image is saved as, rather than what it is called.
- If the type is outside JPEG, PNG and WebP, export a copy in one of them before opening the app.
- Export from the original file, not from a screenshot or a re-photograph of a screen.
- For a set of items, convert every source the same way so the catalogue stays comparable.
Limits of what this page settles
- A file whose reported type is outside the list is refused rather than converted. Getting to an accepted format is something you do before picking the file.
- There is a ceiling a source file has to stay under. It is not stated here; the background remover page carries it, and this page does not put a figure on it.
- Being accepted is not a verdict on the photograph. An accepted file can still be a weak source image, and the gate never claimed otherwise.
- What a generation is instructed to hold on to, and how a piece is framed, is decided elsewhere in the product and is not settled on this page.
- This page describes the app's own gate. It says nothing about what a sales channel asks for when you come to list the finished image.
- The accepted list applies to photographs you bring in yourself. It is not a statement about anything the app produces.
Questions
Which image files does the app accept?
JPEG, PNG and WebP. Whether your file is one of them is decided on your device, before any upload begins, from the type your photo picker reports when you choose the image.
Why was my photo rejected when it looks fine?
Because the decision at that point is a comparison of file types, not an assessment of the picture. If the type reported for the file is not JPEG, PNG or WebP, it is refused before anything is sent — the photograph itself was never examined.
My camera saves HEIC. Will the app accept it?
No. HEIC is not one of the accepted image formats, so the picker reports a type outside the list and the file is refused rather than converted. Export or save a copy as JPEG, PNG or WebP from the original, then pick that copy.
If I rename the file so it ends in .jpg, will the app accept it?
No. The extension in the file name is not what the check reads. The picker still reports the type the file actually is, and that report is what gets compared against the accepted list.
