    What this page does
    Ảnh thẻ (ID-style photo)4 × 6 cm, At least 400 × 600 px, JPG or JPEG. Taken no more than 6 months before you register. No KB limit or background colour is set in the official text

    Checked 2026-11-03. The official notice could not be read directly; values are those attributed to it by several sources that agree. The 400 × 600 pixel minimum and 6-month rule come from the government summary of dispatch 1257; the original document could not be opened. The 4 × 6 shape and JPG format come from Tuổi Trẻ. Photo studios quote limits of 1 MB, 5 MB or 50 to 500 KB; the presets stay within 50 to 500 KB, which passes all of them. Always check the latest official instructions before submitting.

    How to use it

    1. Pick the preset for the file you are uploading.
    2. Drop the photo or scan. Use Crop on its row to frame the face or signature first.
    3. Check the size shown under the preview, then download and upload it.

    THPT exam 2026 (Vietnam): what to upload

    Ảnh thẻ (ID-style photo): 4 × 6 cm, At least 400 × 600 px, JPG or JPEG. Taken no more than 6 months before you register. No KB limit or background colour is set in the official text.

    Other rules to know

    Ministry of Education and Training dispatch 1257/BGDĐT-QLCL (19 March 2026) sets the 400 × 600 pixel minimum and the 6-month limit.

    The photo must be ID-card style (ảnh căn cước).

    Questions

    Why was my THPT registration photo rejected?

    The 2026 rules reject photos smaller than 400 × 600 pixels and photos older than 6 months. A cropped group photo or a selfie at arm's length often fails the first check once it is cropped to 4 × 6. Start from a full-resolution photo; the preset makes it 600 × 900.

    My file comes out smaller than the minimum. What happens?

    Where there is a minimum, the tool first saves at top quality and then adds padding data that image viewers ignore, so the picture is unchanged and the file meets the minimum.

    How accurate are these requirements?

    The official notice could not be read directly; values are those attributed to it by several sources that agree. Rules can change with each new notice, so compare with the official instructions linked on this page.

    Is my photo uploaded to a server?

    No. Everything runs in your browser, so your photo and signature stay on your device. Nothing is uploaded unless you choose to share a file by link. That matters for ID documents. If your device can't handle an image, the tool can shrink it on our server instead, but only if you agree, and it is deleted right away.

    Your images stay on your device unless you share them by link. Ads keep this tool free. If you allow it, our advertising partner Google can use cookies to show you personalised ads and measure them. If you reject, Google shows only non-personalised ads, without advertising cookies. You can change this at any time under "Cookie settings" at the bottom of the page. Privacy policy
