No. Standard resize workflows decode and encode images in your browser using Web APIs. Your files stay on your device unless you choose to download or share them afterward.

Yes. Enter a scale percentage or set explicit width and height. Toggle Maintain aspect ratio when you want proportional scaling instead of a forced canvas size.

PNG uploads download as PNG (transparency preserved). JPG, WEBP, GIF, and HEIC sources export as high-quality JPG unless you started from PNG.

Resize to the required dimensions first, then use Compress Image or a KB preset (for example 50 KB) if the portal also caps file size.

Yes. Enter numeric width and height fields to hit platform requirements such as 1200×630 for social cards, 512×512 for avatars, or 2480×3508 for A4 print drafts at 300 DPI scaling. Percentage mode multiplies both axes uniformly—200 percent doubles, 50 percent halves—useful when batching assets that share the same scale factor. Aspect-ratio lock keeps proportions intact when you change only one axis; the other auto-calculates. This precision matters for government forms that validate dimensions server-side and reject slightly off uploads. Always preview before submitting because some systems measure metadata while others inspect pixel arrays directly.

Downscaling—making images smaller—usually looks sharp because excess pixels are averaged away intelligently. Upscaling within the resizer enlarges beyond the original pixel grid, which cannot invent detail that was never captured. For modest web enlargements, results remain acceptable; for poster prints, start from a high-resolution master or use the dedicated upscale tool afterward. Text and line art show softness sooner than natural landscapes. After resizing down, run compression to meet kilobyte caps, but do that only once to avoid stacked quality loss. Inspect edges at 100 percent zoom before publishing hero images.

No. Dimension changes execute locally through browser canvas operations, mirroring the privacy model of every Rankify image utility. Your files are not uploaded to cloud GPUs or stored in temporary S3 buckets. That design supports legal, healthcare, and education workflows where even transient third-party custody triggers review cycles. You can resize on an airplane after caching the page, or on an isolated workstation without outbound network access. The trade-off is that extremely large panoramas consume local RAM; if the tab crashes, try shorter batches or a desktop browser with more memory headroom.

Crop first when composition matters—tightening a subject before scaling prevents wasting pixels on empty sky or table margins. Resize first when the image already frames correctly but exceeds pixel caps. Combining both in sequence is common: crop to 4:5 storytelling ratio, then resize to 1080×1350 for Instagram portrait posts. Rankify hosts both tools with consistent UX so you can switch pages without learning new controls. Document team standards so interns do not resize aggressively and crop afterward, which can clip important content unexpectedly.
