No installs. No account required for basic tasks. Just drag, set, download.

Bulk Resize
Resize up to 100 images at once. Set one size for all or let the tool scale each proportionally.
Drag-to-Crop
Every thumbnail has its own draggable crop frame. Lock the ratio, auto-frame all, or fine-tune each shot.
Compress to Exact KB
Set a maximum file size target (e.g. 200 KB) and let the tool auto-tune quality to hit it.
Format Conversion
Convert between JPG, PNG and WebP — with HEIC and AVIF input. Batch convert everything in one go.
Watermark
Add text or logo watermarks with custom position, opacity, and size across all images at once.
Social Media Presets
Instant presets for Facebook, Instagram, X, YouTube, LinkedIn and TikTok — always up to date.
100% Private
All processing runs in your browser using Canvas API. Nothing is sent to any server. Ever.
Smart Auto-Crop
Smart detection finds the best frame on every photo — faces and detail stay centered. Free, in your browser.

WHY SWITCH

We did the things others skipped

We built what we wished existed when using other tools.

30 MB files with a free account
Modern photos from mirrorless cameras or iPhones easily exceed 10 MB per file. A free account raises your limit to 30 MB.
No upload means instant processing
Server-based tools waste time on uploads and downloads. We process everything locally — 100 images finish before their progress bar reaches 20%.
Per-image crop, not batch-only
Most bulk tools apply the same crop to every image. We let you drag each crop frame individually — crucial for product photos, portraits, and events.
Always-current social dimensions
Platform specs change quarterly. We update presets when platforms update — no more guessing why your banner looks cropped.

Frequently asked questions

Still unsure? These cover 90% of questions.

Are my images uploaded to a server?
No — never. ImageResizerly uses the browser's built-in Canvas API to process images entirely on your device. No file ever leaves your computer.
Is it really free? What's the catch?
Every tool that runs in your browser is genuinely free: 5 images per batch and 10 MB per file without an account, 20 images and 30 MB per file with a free account. We plan to monetize with a Premium plan for power users and AI features — not by selling your data.
What image formats are supported?
Input: JPG, PNG, WebP, AVIF, GIF (first frame), BMP and HEIC/HEIF from iPhones (decoded on demand). Output: JPG, PNG, WebP — plus AVIF in browsers that can encode it (the option appears automatically).
What are the limits and how do I raise them?
No account: 5 images per batch, 10 MB per file, 150 images per day. Free account: 20 images per batch, 30 MB and 1000 per day. Premium: 100 images per batch, 100 MB, no daily limit. The batch cap keeps browser processing smooth (RAM); the daily cap stops automated abuse — a normal user never hits it.
How does Smart Auto-Crop work?
The Auto-frame button analyses each photo locally (contrast, edges, faces) and positions the crop frame on the most interesting region — free, right in your browser. Upcoming AI features like background removal, OCR and upscaling will use credits on Premium.
