Image Grayscale & Sepia

Resize a PNG, JPEG, or WebP image in your browser — enter an exact target width and height in pixels, or a percentage of the original size, and download the resized result. Aspect ratio is locked by default so width and height scale together proportionally, but it can be unlocked to set both dimensions independently, in which case the image may look stretched or squashed. Enlarging an image beyond its original size is allowed, but it only stretches the existing pixels: it does not add real detail or improve quality, the same way zooming into a photo doesn't reveal anything that wasn't captured. The original file format (PNG, JPEG, or WebP) is preserved in the output, and everything is processed locally using your browser's own image APIs, so no image you resize is ever sent to a server or stored anywhere.

Convert an image between JPG, PNG, and WebP in your browser — upload a PNG, JPEG, or WebP image, choose the output format, and download the converted file. JPEG does not support transparency, so converting an image with a transparent background to JPG fills the transparent area with a white background before export; PNG and WebP output keep transparency when the source image has any and your browser's encoder supports it. Selecting the same format as the source image is blocked, since there would be nothing meaningful to convert. Everything is processed locally using your browser's own image APIs, so no image you convert is ever sent to a server or stored anywhere.

Image Rotate & Flip changes the orientation of a whole PNG, JPEG, or WebP image in your browser, in fixed 90° steps and mirror flips. The buttons rotate left 90°, rotate right 90°, rotate 180°, flip horizontally and flip vertically; a Reset button returns to the original orientation, and the current transform is shown in plain words (for example, 90° clockwise + horizontal flip). Rotations and flips are stored as a small logical state, not as stacked canvas edits, and the preview and the export use exactly the same drawing convention so what you see is what you get. At 90° and 270° the width and height are swapped — a 1200 × 800 image becomes 800 × 1200 — while 0°, 180° and any flip keep the dimensions unchanged; the output size is shown as you work. The exported file keeps the source format (PNG stays PNG, JPEG stays JPEG, WebP stays WebP) and is not resized, cropped or compressed. A 90/180/270 rotation needs no pixel interpolation, but the browser still re-encodes the file: JPEG and WebP are re-encoded, PNG is re-encoded, and EXIF, XMP or ICC metadata may be changed or dropped — this is not a lossless JPEG rotation. Unlike Image Resizer (dimensions), Image Cropper (keeping one region), Image Converter (file format) or Image Watermark (overlaying a mark), this tool only changes the whole image's orientation. Nothing you load is uploaded or stored anywhere.

Image Cropper selects and keeps only a rectangular region of a PNG, JPEG, or WebP image, entirely in your browser. After loading a file, drag the crop frame to move it, drag any of the four corner handles to resize it, or type exact values into the X, Y, Width and Height fields; the frame always stays inside the image. Choose free-form cropping or a fixed aspect ratio — 1:1, 4:3, 3:2, 16:9 or 9:16 — and the frame snaps to the largest centered rectangle of that ratio, without ever distorting the picture. All crop coordinates are stored in the image's own source pixels, not in the on-screen display size, so the selection stays accurate on high-density screens, after a window resize, and in portrait or landscape on mobile. Arrow keys nudge the frame by one pixel (ten with Shift) as a keyboard alternative, and the final pixel dimensions are shown as you work. Cropping does not resize: the output is drawn at the same pixel scale as the source region, and the source file format is kept (PNG stays PNG, JPEG stays JPEG, WebP stays WebP). JPEG and WebP are re-encoded by the browser, so EXIF, XMP or ICC metadata may be changed or dropped; a PNG stays visually lossless but can also lose metadata, and EXIF orientation is not re-applied separately. Unlike Image Resizer, which changes the dimensions of the whole picture, Image Converter, which changes the file format, or Image Color Picker, which reads pixel colors, this tool only trims away everything outside your selection. Everything runs locally, so no image you crop is ever uploaded or stored anywhere.
