Resize without unnecessary uploads
PicTinker uses your browser to resize the image on your device. This keeps the workflow quick and means your original image does not need to leave your device.
When resizing is useful
Resizing helps when a website, marketplace or form requires specific pixel dimensions, when a very large camera image is unnecessary for email, or when you want a smaller image for a profile, post or presentation.
What resizing can and cannot do
Reducing dimensions removes pixels and usually keeps a clean result. Enlarging an image creates more pixels but cannot recover detail that was not present in the original, so large upscales may look softer.
Resize image FAQ
Does resizing reduce image quality?
Reducing dimensions usually preserves a clean result. Enlarging an image cannot create missing detail and may make it look softer.
Can I keep the original aspect ratio?
Yes. Keep aspect ratio is enabled by default, so changing one dimension updates the other proportionally.
Are my images uploaded?
No. Supported images are processed locally in your browser.
