Upload your image, set Maximum File Size to 100 and the unit to KB, then click Compress. In Auto quality mode the tool binary-searches for the highest quality that keeps the output under 100 KB, and reduces dimensions only if needed.

Resizing changes the pixel dimensions (e.g. 4000×3000 → 1920×1440). Compressing reduces file size at the same dimensions by lowering quality or switching to a more efficient format like WebP. Sukat does both — it compresses first and only resizes when it can't hit your file-size target otherwise.

At very low quality settings, or with complex noisy images, JPEG's older compression can occasionally produce smaller files than WebP. For most photos WebP wins by 25–35%. If file size matters more than format, try both and keep the smaller one.

Auto mode binary-searches for the highest quality that fits within your max file size. If even the lowest quality would still exceed the limit at your target width, it reduces dimensions as a last resort so you always get a file under the cap. When that happens, the live preview shows the actual output dimensions and a soft-orange callout explains the trade-off — keep Auto for a smaller image that meets the limit, or raise the size limit (or drag the slider above Auto) to keep the full width and accept a larger file. You always know what you'll get before downloading.

No. All processing happens locally in your browser using the Canvas API. Nothing is sent to a server, and no account or sign-up is required.

No hard limits. Because everything runs in your browser, the practical ceiling is your device's RAM — very large files (100+ MB RAW exports) may be slow on older devices but are otherwise supported.

Yes. A “View compression report” link below the Compress button opens a modal listing every successful compression done on this device — original and output filename, dimensions, size, quality, and timestamp. Records live in your browser's localStorage (capped at 500 entries, newest first), never on a server. The modal supports date filtering, pagination, per-row selection, Copy to clipboard (styled HTML table plus markdown fallback), and Download CSV (Excel-compatible UTF-8 BOM). A Delete All Data button wipes the entry after confirmation. Only metadata is stored — never the image bytes.

Most Windows and Android devices don't display HEIC natively. Convert HEIC to JPG or PNG here before sharing — the tool handles iPhone HEIC files even on non-iPhone browsers.

Yes. Pick ICO (favicon, square) as the output format, set Target Width to the icon size you need (16, 32, 48, 64, 128, or up to 256), and click Compress. Sukat letterboxes non-square sources into a transparent square so logos aren't distorted, then encodes a Windows-compatible ICO you can drop in as /favicon.ico. The same file works for desktop shortcuts, pinned tabs, and taskbar icons. Everything happens in your browser.

Yes. With exactly one image selected, a Crop button appears next to its filename. It opens a cropper with draggable corner handles and aspect-ratio presets (Free, 1:1, 16:9, 4:3, 3:4). Apply Crop replaces the source file in the list, so the subsequent compression and download use the cropped version. Use arrow keys for 1-pixel precision or Shift+arrow for 10-pixel jumps. Cropping happens entirely in your browser.

Yes. For a single selected image, click Paint next to the filename. The editor has three tools sharing one canvas — a brush (paint a solid colour or pick the transparent swatch to erase to alpha, with size 2–200 px and edge feather sliders), a text tool (click to spawn editable text; size 8–400 px, five font families, Bold/Italic/Underline, colour), and an image-overlay tool (drag corners to resize with aspect ratio preserved). Everything shares one undo/redo stack up to 10 levels. A zoom slider (5–800%), Fit, Ctrl/Cmd+scroll zoom, and a Pan toggle handle pixel work. Apply saves as [original]-painted.png; Revert restores the original. All rasterises locally before download.

Sukat dedupes the action tags it appends. Each editing action stamps the name (-cropped after Crop, -painted after Paint, -nobg after Remove BG, -compressed on convert) but the same tag never appears twice — if you crop an already-cropped file the second action replaces the first tag instead of stacking. Custom filenames you type into the Output filename field aren't affected.

Yes. The Output filename (optional) field above the Compress button overrides the default [original]-compressed name. The value is sanitised (illegal characters and control bytes stripped, spaces to hyphens, capped at 80 characters) and used as the stem. Single image → [your-name].[ext]; batch → [your-name]-1.[ext], -2, etc. ZIP downloads use [your-name].zip. Leave it blank for default behaviour; the field clears after each download.

No. Clicking Remove BG opens the modal in a preview phase — the original renders into the canvas with zoom, fit, and pan for inspection. A Remove background button kicks off the AI run only when you press it. After the cut-out is produced you also get a manual eraser brush inside the modal to clean up leftover halos before clicking Apply.

No. When you click Remove BG, Sukat first scans the source's alpha channel. If any pixel is already partially or fully transparent (typical for PNG, WebP, AVIF, or GIF cut-outs) it skips the 40 MB model download entirely and goes straight to the feather + background-colour controls. JPEG sources never have alpha, so they always use the model.

Yes. The Remove BG modal includes an Edge feather slider (0–20 px) that softens the alpha edge with a Photoshop-style feather. Sukat builds a blurred silhouette mask and multiplies it back into the original alpha via destination-in compositing, so the boundary fades inward smoothly with no halo, fringe, or colour shadow. Useful when the model leaves a hard edge against busy backgrounds. The feather and the optional background colour combine into the same applied PNG.

Yes. After Remove BG produces the transparent cut-out, a row of preset swatches (white, black, brand green, blue, red) plus a colour-wheel picker appears below the preview. Click any preset or open the picker to composite the cut-out over a solid colour — the preview updates live as you drag. Click the checkered transparent swatch to revert. Whatever you Apply is saved into the file, so the rest of the pipeline handles it identically.
