In the digital era, images play a crucial role in communication, marketing, social media, websites, and even personal archiving. But often, these images come in sizes or formats that don’t match the requirements of their target platforms. Whether you’re a photographer handling thousands of RAW photos, a business owner managing product images for an e-commerce website, or a designer preparing files for print and web, resizing images in bulk becomes an essential task.
This is where a Batch Image Resizer becomes a game changer. Unlike manual resizing tools that require you to adjust each image individually, a batch image resizer allows you to process hundreds or even thousands of images at once. The resizer is not only fast but also versatile, supporting 100+ image formats to ensure seamless conversion and resizing for any project.
The tool support for various resizing methods:
➤ By Percentage: Scale images relative to their original size.
➤ By Width: Height will be auto-resized (original aspect ratio is maintained)
➤ By Height: Width will be auto-resized (original aspect ratio is maintained)
➤ By Width- Height: Resize to fixed dimensions (original aspect ratio is not maintained)
The tool supports the most commonly file types, including:
🖼️ Raster Image Formats: jpeg/jpg, png, gif, bmp …
📷 RAW Image Formats: nef, cr2/cr3, arw, orf, dng …
🎨 Vector Image Formats: ai, svg, eps …
🌐 Other or Specialized Formats: heic/heif, ico, webp, psd …
The ability to resize across these formats dramatically enhances the flexibility of your image management workflow. And here is the full list of 100+ image formats supported by the resizer:
3fr, aai, ai, apng, art, arw, avif, avs, bmp, bmp2, bmp3, cin, cr2, cr3, crw, cur, cut, dcm, dcr, dcx, dds, dib, dng, dpx, emf, epi, eps, eps2, eps3, esf, epsi, ept, ept2, ept3, erf, exr, fax, ff, fff, fit, fits, fl32, fts, g3, gif, gif87, hdr, heic, heif, hrz, icb, ico, icon, ipl, j2c, j2k, jfif, jng, jp2, jpe, jpeg, jpg, jpm, jps, jxl, k25, kdc, mac, mat, mdc, mef, mif, miff, mng, mos, mrw, mtv, nef, nrw, odd, ora, orf, otb, palm, pam, pbm, pcd, pcds, pct, pcx, pdb, pef, pes, pfm, pgm, pgx, phm, picon, pict, pix, pjpeg, png, png00, png24, png32, png48, png64, png8, pnm, ppm, ps, psb, psd, ptif, qoi, raf, ras, raw, rgb, rgf, rla, rle, rw2, rwl, sgi, six, sixel, sr2, srf, srw, sun, svg, tga, tif, tiff, tiff64, tim, vda, vicar, viff, vips, vst, wbmp, webp, wmf, wpg, xbm, xcf, xpm, xv.
To meet various needs, the tool supports multiple output formats. Users can choose the format that best suits their goal: bmp, emf, exr, gif, ico, jpeg 2000 (j2k, jp2), jpeg, jpg, pdf, png, psd, svg, tga, tiff, webp.
For output .ico format, users can pick any custom dimensions, e.g., 32×32, 64×64, 128×128, etc.
The challenge lies in maintaining image quality during resizing. A naive scaling approach can result in blurry edges, pixelation, or loss of detail. This is where interpolation methods come into play. Interpolation defines how new pixel values are calculated when enlarging or reducing an image. Different methods produce different results depending on the image content and the target use case.
By supporting multiple interpolation methods, our resizer allows users to select the method that best suits their project. One method rarely fits all needs. Let’s break down the most widely used interpolation techniques in batch resizing:
1️⃣ Nearest Neighbor:
➤ Simplest method. Each new pixel copies the value of the closest existing pixel.
✔️ Pros: Fast, preserves sharp edges for pixel art.
❌ Cons: Produces blocky, jagged edges when enlarging.
2️⃣ Bilinear:
➤ Considers the 2×2 neighborhood of pixels and averages them.
✔️ Pros: Smoother than nearest neighbor.
❌ Cons: Slightly blurry, loses sharpness.
3️⃣ Cubic:
➤ Considers a 4×4 neighborhood for interpolation.
✔️ Pros: Produces smoother and more natural results.
❌ Cons: More computationally expensive.
4️⃣ Lanczos:
➤ Uses sinc-based filters over a larger neighborhood.
✔️ Pros: High-quality resampling with sharp detail preservation.
❌ Cons: Slower, may introduce ringing artifacts around edges.
The resizer also provides format conversion options to tailor outputs:
➤ Adjust compression levels for JPEG, IPEG 2000 or WebP to balance file size and image quality.
➤ Use lossless compression for PNG or TIFF when quality is paramount.
➤ Preserve or convert color profiles (RGB, CMYK) for TIFF.
