How to resize images without guessing the result
Choose up to 30 JPG, PNG, or WebP images and apply one clear sizing rule to the group. Set a width when every image must fit the same column, a height for a consistent row, a percentage for proportional scaling, or a maximum box when both dimensions matter. “Fit inside” keeps the entire picture visible. “Fill and crop” covers the requested box and trims equal areas from the long sides. Exact dimensions can preserve the original proportions or create the precise width and height you enter.
Before processing, the workspace shows the first image’s original and expected dimensions. The “do not enlarge” option protects smaller files from unnecessary upscaling. Choose the original file type or convert the new copies to JPEG, PNG, or WebP. JPEG suits photographs, PNG preserves transparency, and WebP can be useful for modern websites. Quality affects JPEG and WebP compression; it cannot restore detail that was absent from the source.
Choosing between fit, fill, exact size, and percentage
Fit is the safest default for mixed photographs because every result stays inside the requested box without stretching or cutting off content. Fill is useful for cards, thumbnails, and product grids that require one exact shape, but it deliberately crops the source around the center. Width-only and height-only modes are useful when one layout dimension is fixed and the other should follow the original proportions. Percentage is best for making every file half-size or creating a larger working copy with the same aspect ratio.
A batch can contain landscape and portrait images. The same rule applies independently to each source, so a 1600 by 1200 fit box may produce 1600 by 900 for one photo and 800 by 1200 for another. Review the per-file dimensions after processing instead of assuming every result will match. If one file is malformed or unsupported, successful files remain available and the failed item is identified in the batch report.
Privacy, quality, and browser limits
Images are decoded, resized, and encoded in the current browser tab. They are not uploaded to NexaCurrent, attached to an account, or placed in the page address. A single result is shown as a preview; multiple results are packaged into a ZIP download. Temporary previews are released when you replace the files, clear the result, close the page, or leave the tool. Keep the originals because every resize creates new pixels and may change compression or metadata.
Each source is limited to 30 MB and 40 megapixels, a batch is limited to 30 files, and an output cannot exceed 40 megapixels. These limits reduce the chance that decoded pixels exhaust the device’s memory. Resizing can make dimensions larger, but it does not create trustworthy fine detail or repair blur. For print, archival, medical, forensic, or color-managed work, inspect the export in the specialist application and profile used by that workflow.
