Resize, crop, and convert images without uploading them

Every image job begins with a constraint set by something else—a page layout, an avatar box, a marketplace listing, an upload form. Write that constraint down before you touch the file, because it decides the order of every step that follows.

• DimensionsPixel dimensions: the layout slot or platform requirement, such as a 1200×630 social card, a 512-pixel avatar, or a product photo that must stay crisp on high-density screens.
• Size budgetFile-size budget: an email attachment cap, a portal that rejects anything over two megabytes, or a performance budget for a page that has to stay fast on a slow connection.
• Format acceptanceFormat acceptance: some systems take only JPEG or PNG, while modern pipelines reward WebP. Converting to a format the destination cannot read is wasted work, however small the file gets.

Cropping removes pixels you never needed, which fixes the composition and shrinks the file before any resampling happens. Cropping after the resize means spending interpolation effort on detail you were about to throw away, and a crop locked to the destination’s aspect ratio guarantees the framing survives.

Image Cropper cuts an exact numeric region or constrains the selection to a common aspect ratio, so the framing matches the destination slot before a single pixel is rescaled. It accepts PNG, JPEG, and WebP files up to 12 MiB each, with sides up to 8,192 pixels and 24 million pixels in total, and it exports the cropped result directly as PNG, JPEG, or WebP.

A practical order for most jobs: open the original, crop to the final aspect ratio, and only then think about dimensions. If the crop alone brings the file under the byte budget, you may not need to resize at all.

Every downscale discards information, so chain as few resamples as possible: start from the highest-quality original available and go straight to the target size in one pass instead of stepping down through intermediate sizes.

Image Resizer applies high-quality interpolation locally and can lock the aspect ratio so one dimension follows the other—type the width the layout expects and the height stays proportional. A single file can be up to 12 MiB, 8,192 pixels per side, and 24 million pixels overall.

When a whole set of photos needs the same treatment, batch mode resizes up to twelve images and 96 MiB in total, one file at a time, and packs the results into a single download. Keep the originals: a resized copy is a delivery artifact, not a master, and scaling it back up later cannot recover the discarded detail.

Format is a compression decision, not a file-extension preference, and the right choice depends on what is inside the picture.

Image Format Converter accepts PNG, JPEG, WebP, GIF, and AVIF sources and exports PNG, JPEG, or WebP, reporting the before-and-after byte sizes exactly as measured—so the trade-off is a number, not a guess.

• PNGPNG is lossless and preserves transparency—best for logos, interface screenshots, and flat graphics with sharp edges—but it stays heavy for photographs.
• JPEGJPEG is lossy and small for photographs and smooth gradients; it carries no transparency, and re-saving it repeatedly compounds visible artifacts, so convert once at the end.
• WebPWebP usually beats both on size at comparable quality and supports transparency, but confirm the destination accepts it before committing an entire delivery set.

When the limit is megabytes rather than pixels, work in order—crop, resize, then convert—and measure at each step instead of guessing. Pixel area dominates file weight: an image twice as wide and twice as tall as needed carries roughly four times the pixels.

Measure the exported bytes, not the progress bar: the resizer and the converter report sizes exactly as produced, so the number you verify against the budget is the number the destination will see.

• Resize firstHalve both dimensions and a photograph typically loses about three quarters of its pixel count, which is usually the single biggest saving available.
• Then re-encodeSwitching a photographic PNG to JPEG or WebP often saves more than any further resize, at a quality cost that is invisible at delivery size.
• Mind transparencyKeep transparency in the decision: flattening a logo to JPEG to save bytes destroys the alpha channel the layout depended on.

The image delivery workspace chains these steps into one ordered flow—set the delivery limits, process locally, then verify and export—so the sequence stays consistent across a whole set of assets.

It combines resize, crop, and format conversion with a file-size ceiling target and removal of supported metadata, taking a photo from camera original to a verified delivery package without leaving the tab. Download the result before closing the workspace; local tools keep no cloud copy, and the original on your disk stays byte-identical throughout.
