MAKE ROOM FOR THE DETAILS
A little larger.
A carefully judged finish.
01 / THE ORIGINAL
Enlarge an image 2× or 4× with bicubic interpolation, then adjust its sharpness, noise and exposure.
One still image · 20 MB maximum · 24 MP input. Output: up to 12 MP and 8,000 px per edge. Large originals may need resizing first.
Your image stays on this device. This tool uses interpolation and image filters, not AI or recovered detail.
02 / A CAREFUL FINISH
Choose an image to see its output dimensions.
Enlargement interpolates existing pixels. It does not reconstruct missing detail. Strong filtering may introduce halos or soften texture.
Add an image or try the sample to get started.
Add an image, choose an enlargement and adjust the finish. Process the photo, compare the previews and download a PNG or JPG. A 2× enlargement doubles each dimension and uses four times as many pixels; 4× uses sixteen times as many.
This tool uses bicubic interpolation, edge-aware local smoothing, exposure adjustment and unsharp masking. It does not use a neural model or invent new image detail. Adjust the controls gently and inspect the result. A sharper edge is not evidence of a more accurate image.
No. It uses traditional interpolation and image filters in a Web Worker. It can make an image larger and change its appearance, but cannot recover detail that was never present. No image is sent to an API or server.
The input must be a still JPG, PNG or WebP image of 20 MB or less, with at most 24 megapixels. The enlarged output must fit within 12 megapixels and 8,000 pixels per edge. A large original may exceed the output limit at 2× or 4×; resize it first with the Image Compressor.
PNG output preserves the interpolated transparency. JPG places transparent regions on white. Re-encoding removes original metadata and may change color handling. Keep your original, especially for editing or printing.
Start with 2× and light sharpening. Increase noise reduction only if the source looks grainy; it may remove useful texture. Exposure changes brightness in linear light over a range of −1 to +1 EV. Large adjustments can clip bright colors. JPG is encoded at 92% quality; PNG uses lossless encoding of the processed pixels.
