Bulk Image Resize

Workforge Bulk Image Resize is a free browser-based tool for resizing and converting hundreds of images at once. Drop in a folder or multi-select files, choose your target dimensions or aspect ratio, and download a ZIP of resized and converted images. It is built for anyone who deals with images in bulk: ecommerce sellers cropping product shots, marketers preparing social posts, designers processing client folders, photographers exporting shoots, and developers building responsive image sets. Sources can be JPG, PNG, WebP, AVIF, or HEIC. Output can be any of those or a mix. There is no upload, no cap on batch size, and no watermark on the output.

Presets include Instagram (square, portrait, story, reel), LinkedIn (banner, post, avatar), Amazon and Shopify product images, Twitter and Facebook headers, and standard print sizes. Or type in a custom width and height. If the source aspect ratio differs from the target, choose contain (letterbox), cover (crop to fill), or stretch. Cover mode uses a lightweight face-detection model to keep faces and prominent subjects centered when cropping.

The output format is your choice. Keep original, force all to JPG for smaller file size, PNG for lossless, WebP for maximum efficiency, or AVIF for cutting-edge compression. Mixed-source batches - a folder that contains JPG, PNG, and HEIC together - all convert cleanly to a single unified output format. EXIF and color profiles pass through by default; a single checkbox strips them for privacy or smaller size. Filenames follow a template you control so output never overwrites input by accident.

Bulk image resizing is a routine task that should not cost anything or hand your files over to a third party. Almost every paid competitor exists because they run image processing on their servers, and servers cost money to run. Workforge Bulk Image Resize runs entirely in your browser using the Canvas API and WASM - no server processing, no per-file cost to us, no reason to charge you.

Workforge's business model is straightforward: free browser-based tools funded by paid products (Flow, Clausebox) that share infrastructure. The bulk resizer, the file identifier, the favicon generator, and every other tool in the suite are permanently free. No hidden 'convert your first 5 files free, pay for the rest' trap. No freemium tier that removes essential features. No signup wall.

Ecommerce sellers preparing product photos. Amazon requires specific dimensions, Shopify wants square hero images, Etsy has its own preferred aspect ratios. Instead of resizing each product photo individually in Photoshop or Preview, drop the whole folder, pick the platform preset, and get correctly-sized images in seconds. Bulk convert HEIC iPhone photos to JPG in the same pass.

Marketers and social media managers preparing platform-specific creative. A single hero image often needs Instagram square (1080x1080), Instagram story (1080x1920), Facebook cover (820x312), Twitter card (1200x628), and LinkedIn post (1200x627) exports. Drop the source, run four presets, done.

Photographers exporting shoots for review. Downscale to a manageable web size, batch strip EXIF (removing camera and GPS data), and produce a ZIP for client review or upload to a portfolio.

Developers building responsive image sets. Producing multiple resolutions (retina 2x, 3x) or format variants (WebP alongside JPG for browser fallback) from a single source is a common web performance task. Do it as a one-time batch rather than wiring up a build pipeline for a small project.

Anyone with a folder of iPhone HEIC files that a colleague or client cannot open. Batch convert to JPG in one drop.

Photoshop's batch actions and Image Processor are the professional standard: powerful, scriptable, integrated with the rest of the Creative Cloud pipeline. If you already have Photoshop, you have this capability. If you do not, the entry point is a $22.99/month Creative Cloud subscription.

For most bulk resize jobs, that is overkill. You do not need layer effects, color grading, or scriptable actions to take 200 product photos, resize them to 1600 pixels wide, and save them as WebP at 85% quality. You need one screen, four settings, and a Process button. Workforge Bulk Image Resize does exactly that.

Where Photoshop wins: complex per-image transformations, color-critical work, and integration with Lightroom catalogs. Where Workforge wins: speed of one-off jobs, zero cost, no software install, privacy (your files never leave your browser), and no learning curve. Use whichever fits the task.

Every other free bulk image tool online asks you to upload your files. That means every image you process - product photos with pricing information visible, personal photos, client work under NDA, screenshots with sensitive data - passes through someone else's server and is subject to their privacy policy, data retention rules, and breach risk.

Workforge Bulk Image Resize runs entirely in your browser. When you drop images into the tool, JavaScript reads them locally, resizes and converts them locally, and packages the results into a ZIP that downloads directly. No network request touches your image data. No server sees your images. Nothing is logged. Close the tab and the images are gone from the tool's memory.

For sensitive work - unreleased product photos, client images under NDA, personal images you would rather not hand to a third party - this materially reduces exposure. For everyday work, it also means faster processing (no upload wait), no rate limits, and no server queues.
