01What is Image Resizer?
Resize photos by width, height, percentage, platform preset, or target file size—with instant preview for JPG, PNG, and WebP. Resize image online free with ImgifyTools — enter exact pixel dimensions, scale by percentage, or pick a social media preset for Instagram, YouTube, Facebook, and LinkedIn. Lock aspect ratio to prevent distortion, batch-resize multiple files, and download in JPG, PNG, or WebP. Bloggers hit exact theme widths like 1200px. Developers export icon sizes from one master. HR teams resize headshots for intranet directories. Unlike careless stretch handles in presentation software, this image resizer uses high-quality downscaling interpolation to preserve detail when shrinking photos. Optional compression after resize hits byte budgets for form uploads. Free, browser-based, unlimited resizing with instant preview. Pair with resize-to-KB tools for government portal file size limits.

05Resize by Pixels, Percentage, or cm/mm/inch
Enter exact pixel width and height for web and app assets — common targets include 1200×630 for link previews, 1920×1080 for HD, and 512×512 for avatars. Scale by percentage to halve or double dimensions proportionally. For print-adjacent workflows, convert between pixels and physical units (cm, mm, inch) using your target DPI. Aspect ratio lock ensures changing one dimension adjusts the other automatically, preventing stretched faces or logos.
06Social Media Size Presets (Instagram, YouTube, Facebook)
One-click presets eliminate memorizing platform dimension charts. Instagram feed square (1080×1080), story/reel vertical (1080×1920), Facebook link preview (1200×630), LinkedIn post (1200×627), and YouTube thumbnail (1280×720) are available as presets. Select a preset, upload your image, and download a platform-ready file. For dedicated YouTube sizing, use our YouTube Thumbnail Resizer tool.
07Resize Without Losing Quality — How It Works
When you downscale an image (make it smaller), the resizer uses high-quality Lanczos or bicubic interpolation to average pixel data intelligently — preserving edges and reducing moiré patterns. Upscaling beyond source resolution cannot add real detail; the tool warns when you exceed original pixels. For AI-powered enlargement, pair with our image upscaler. Chain resize then compress for optimal CMS upload sizes.

Frequently Asked Questions
Downscaling (making an image smaller) preserves quality when using high-quality interpolation. Never upscale small images for print — use our image upscaler for AI enlargement instead.
ImgifyTools image resizer offers exact pixels, percentage scaling, social presets, aspect ratio lock, and bulk resize — all free with no watermark or signup.
Yes. Upload multiple images, apply the same dimensions or preset, and download all resized files. Use our platform image resizer hub for one-click social presets across batches.
Enter your target width and height in pixels. Enable aspect ratio lock if you only want to change one dimension. The tool calculates the other side automatically.
Resizing changes the total pixel dimensions of the entire image. Cropping cuts away portions of the image to a new frame. Use our image cropper when you need to remove edges, not scale the whole photo.
JPG, PNG, and WebP uploads are supported up to 10 MB. For strict portal KB caps, pair with our resize-to-20KB or image compressor tools after setting pixel dimensions.
