Let me start with the conclusion: phone selfies can indeed directly generate multi-size white-background ID photos. The framing and cropping are basically usable, and the person's features hold up at the "looks like me" level. But hair edges, shoulder-line symmetry, and clothing details still require manual intervention. Pure one-click output is only suitable for scenarios with low precision requirements.
My own situation: last month I needed a photo for a residence permit receipt, a company badge update, and an online registration form. All three required different sizes—one-inch, two-inch, and a small two-inch. In the past I would have made multiple trips to a photo studio. This time I decided to try selfies on my phone. Over about two weeks, I tested two or three mainstream ID photo tools, and tried three shooting methods: indoor natural light, a white wall background, and having a family member press the shutter with the rear camera. Here's my experience.
**Pro one: multi-size cropping is genuinely convenient.** My original shot was portrait orientation with the person slightly left of center. Selecting "one-inch" automatically framed the face slightly above center, and switching to "two-inch" adjusted the headroom and shoulder proportions accordingly—not just a uniform scale-down. The clearest example: the one-inch photo for my badge was exported directly and submitted without being rejected. HR only said "as long as the background is white enough."
**Pro two: facial features are preserved better than expected.** I have a round face and a short chin, and I worried that auto retouching would turn me into an influencer-style face. In practice, most tools only apply light skin smoothing and brightening by default. Moles, double-eyelid creases, and the hairline shape all remained. I used my mom as a reference—she glanced at it and said, "That's you, no ridiculous retouching." That assessment was good enough for me.
**Pro three: edge handling for white-background replacement has improved.** My wall isn't pure white—it's beige-ish—but the tool could cut out the background and replace it with standard white. I have short hair with some stray strands at the temples. The first version had jagged edges, but after switching to "fine cutout" mode, the stray hairs were preserved much more naturally. That's how the residence permit receipt photo was produced. The print shop owner said, "It'll work."
**Con one: shoulder lines and collars tend to be crooked.** When taking a selfie, you're holding the phone up, so your shoulders naturally sit at different heights. After the tool auto-straightens the face, the shoulder line doesn't get corrected along with it. In one shot where I wore a shirt, the left shoulder was noticeably lower than the right after export, and one side of the collar was folded while the other lay flat. I ended up standing straight against the wall and having a family member retake it. Pure selfie output isn't very reliable on this point.
**Con two: after switching sizes, the framing sometimes "crowds the head."** With the small two-inch spec, the headroom got compressed very narrow after switching—my forehead was almost touching the edge. The same original image cropped to one-inch was fine, which shows the headroom rules aren't consistent across size templates. My workaround was to export the one-inch first, then manually adjust the position and export the small two-inch. It took an extra minute or two but saved me from having to redo it.
Who this suits: if you need a photo for a receipt, badge, or registration form—something that just needs to "pass"—selfies plus a tool are completely sufficient. Just remember to find a clean wall, have a family member press the shutter, and don't hold the phone yourself. If you're submitting for a visa, passport, or official file that has strict requirements for shoulder lines, headroom, and clothing, I'd recommend going to a studio, or at least having someone check your framing after you shoot. The tools themselves aren't bad—it's just that "fully automatic" still deserves an asterisk.
