关于我们图像缩放器的常见问题

是的！您可以完全免费调整图像大小。支持最大 5 MB 的 JPG、PNG 和 WEBP 格式。
我们使用先进的算法来保持最高画质。虽然缩小图片时细节难免会有少许损失，但我们的工具已将其降至最低。
上传的图片会在处理并下载后自动从服务器上删除。您的隐私是我们的首要任务。
Not if you do it right. Our tool uses smart resampling, so shrinking a photo down keeps the details sharp instead of turning it blurry or pixelated. If you are going from a huge camera photo down to something small for the web, you honestly would not notice much difference in clarity — you will just notice the smaller file size.
No, nothing at all. It runs right in your browser tab. Open the site, drop in your photo, resize it, and you are done — no app store, no plugin, no software eating up space on your laptop or phone.
It is free, full stop. No hidden paywall after your third resize, no watermark slapped on your image, and no account needed. You can resize as many photos as you want without ever being asked to pay or sign up.
This is the part people usually worry about most, and fair enough. Everything happens locally on your own device — your photo never actually gets sent to a server. So there is nothing sitting on our end to leak, get hacked, or accidentally end up somewhere it should not.
Both, actually. If you know you need something like 1200×630 for a blog header, just type those numbers in. If you just want it "a bit smaller" without doing math, drag the percentage slider instead and watch the size update live.
It would not, as long as you leave the aspect ratio lock turned on. That keeps height and width scaling together automatically, so your photo stays proportional instead of getting squished or stretched out of shape.
Yep, that is actually one of the more common uses. Shopify (and most eCommerce platforms) prefer specific dimensions for product images, and this tool lets you knock out several photos quickly before uploading, so your storefront looks consistent instead of mismatched.
Works fine on mobile. The site is responsive, so whether you are on an iPhone, Android, tablet, or desktop, the layout adjusts and everything still functions the same — upload, resize, download.
Right now this covers single images cleanly, but if you are doing product listings or a batch of social posts, there is a bulk resizer tool built for exactly that so you are not repeating the process 20 times manually.
JPG, JPEG, PNG, and WEBP are all covered. So whether your photo came straight off a phone camera, was exported from Photoshop, or is one of those newer WebP files from a website, you are not going to hit a "format not supported" wall.
