What 500 × 500 is
500 × 500 is square thumbnail — a 1:1 frame, 0.3 MP in total. It shows up in square thumbnails in grids and listings. The shape matters more than the numbers: a photo already at 1:1 drops into this frame with nothing stretched, while a photo at any other ratio gets squeezed unless you crop it first.
Resize a photo to 500 × 500
Drop one above. The editor opens with a resize step already filled in with 500 and 500, so the next thing left is the download. PIXLFLW does the work inside your browser — no upload, no queue, no account, and the file never leaves the device.
If your photo is not 1:1
Then forcing it into the frame stretches the picture, and faces show it first. Add a crop step before the resize, pick the 1:1 preset, choose the part of the shot worth keeping — the resize then lands on 500 × 500 in proportion.
Will it stay sharp?
Scaling down to 500 × 500 from a larger original is effectively lossless: high-quality resampling discards pixels smoothly and the result looks crisp. Scaling up is the harder direction — no tool can restore detail the camera never recorded, though enlargements up to roughly double the original still hold together. The editor shows the source dimensions next to the target so you always know which direction you are going.
Exact pixels and a file-size limit at once
Many upload forms cap both: 500 × 500 and a maximum weight in KB. Do the resize here, then switch on Target file size in the download dialog and type the limit — the encoder searches for the best JPEG quality that still fits and reports the real byte count before you save.
Formats and cost
JPG, PNG, WEBP, GIF and HEIC go in; JPG, PNG, WEBP or GIF come out. Free, unlimited, no watermark and no sign-up — resize one image or fifty, one after another.
People type this size a few different ways, such as 500x500, 500 x 500, 500×500, 500*500, 500+500, 500 500. They all point to the same photo dimensions.
