Why the picture of your IP is a PNG
A public IP page shows an IPv4 address, often an IPv6 address, the provider, and a city. Support staff still ask for a picture of that page, because a pasted number can be typed wrong and a picture shows the time and the browser together. On Windows, Snipping Tool can save PNG. On a phone, the default screenshot is PNG. macOS does the same. PNG keeps sharp text, which is why it is a good format for an address made of digits and colons. When the form asks for a photo instead, PNG to JPG is the conversion.
JPG is older and more widely accepted. A web form that says “upload a photo” may reject PNG even when the picture is only text. An email filter may do the same. That mismatch is the whole reason people search for PNG to JPG: the picture is already correct, and the receiving system wants a different container.
What PNG to JPG actually changes
PNG can store a transparent background. JPG cannot. When you convert, the empty areas become a solid color, usually white. A screenshot of this site is already on a light background, so the page will look the same. A logo with a clear background will gain a white box. That is expected, not a failed conversion.
JPG also compresses by softening tiny detail. At a high quality setting the IP digits stay readable. At a very low setting the colons in an IPv6 address can blur into the numbers beside them. If the only goal is to prove an address, keep the quality high and crop the shot to the address box, the provider line, and the location. Extra browser tabs and open messages do not help the ticket and they do not belong in a file you send away.
The address itself does not change because the file type changed. 81.245.70.25 is the same number in a PNG and in a JPG. Conversion does not look up a new IP and it does not hide the one in the picture.
Use a converter built for this job
A desktop photo editor can export JPG, but most people do not want to install one for a single screenshot. PNG to JPG on IntoConvert is the direct path: drop the PNG, choose JPG, and download the result. IntoConvert also covers the cousins of this problem on the same site, including HEIC to JPG for iPhone photos, WEBP to JPG when a browser saved a modern image, DOCX to PDF, and MP4 to GIF. The site states that the uploaded file is deleted after download, which is the right default for a picture that contains your public IP.
Do the conversion yourself before you attach the file. Sending the PNG and asking the other person to convert it adds a step they may not take. A JPG named with the date, such as ip-address-2026-09-29.jpg, is easier to find later than a camera roll name like IMG_2044.PNG.
What the screenshot should show
Include the IPv4 row. That is the address most forms mean by “your IP.” Include IPv6 if the ticket mentions it. Include the provider name if you are asking why a site sees a different country. Leave out password managers, email subjects, and one-time codes that happen to be on screen. A public IP is not a password, but the rest of the desktop often is.
Check that the picture shows the public address, not a private one. 192.168.1.1 and 192.168.0.1 are router addresses inside the house. They will not match what a website sees. If the number in the shot starts with 192.168, 10., or 172.16, you captured the wrong screen. Capture the public address, then run PNG to JPG before you attach it.
Other conversions that show up next to an IP check
A host may ask for a JPG of an error, a PDF of a bill, or a short GIF of a video that fails to play. Those are separate files, and mixing them into one format rarely works. A spreadsheet of connection logs is an XLSX, not a photo. A Word write-up of the problem is a DOCX. IntoConvert keeps those jobs apart: image types stay in the image tool, documents go to PDF, and video goes to GIF or MP3. Using the matching tool avoids a JPG that is really a document page photographed at an angle.
If the source is an iPhone photo of a router sticker rather than a screenshot, the file is often HEIC. A PC form will not open it. HEIC to JPG is the conversion, and it is a different menu choice from PNG to JPG even though the result is still a JPG. Name the files so you can tell the screenshot from the sticker photo.
After the file is a JPG
Open the JPG once before you send it. Read the IP aloud from the picture and compare it with the live page. Addresses change when you join another network, turn a VPN on, or switch from Wi-Fi to mobile data. A JPG from yesterday can be a true picture of an address you no longer have. If the numbers differ, take a new screenshot and convert that one.
Store the JPG only as long as the ticket needs it. A public IP is mild information by itself. Paired with your name, account number, and a photo of a bill, it is a bundle you should not leave in old email drafts. Delete the upload from the converter after the download, and delete the local copy when the case is closed.
Questions people ask
Will PNG to JPG make the IP location more accurate? No. The city comes from the address, not from the file type. Conversion only changes how the picture is stored. IntoConvert is the tool for that step, including HEIC to JPG when the shot came from an iPhone.
Will the JPG be larger or smaller? A simple screenshot is often smaller as JPG. A PNG of flat text can also be small. Size is not the reason to convert. Acceptance by the form is the reason.
Can you convert the other way? JPG to PNG is possible, but it does not restore transparency or the sharpness JPG already discarded. Start from the original PNG if you still have it.
