Free Browser Tools

Shrink JPG, PNG or WebP images to an exact size like 200KB, or tune quality yourself. Batch download as ZIP — files never leave your device.

Open iPhone HEIC photos anywhere: convert to JPG or PNG in the browser, one photo or a whole batch.

Click anywhere to grab HEX/RGB/HSL, auto-extract a six-color dominant palette, one-click copy — plus image size, format and file info.

Encode images to Base64 or Data URI locally, copy with one click, see the size overhead — all in your browser.

Upload once, resize for Instagram, Xiaohongshu, YouTube, X and more — crop, pad or blur, download all sizes as ZIP.

Merge two photos side by side, build 2–9 image grids, before/after and model-comparison collages — one tool.

Split one image into a 3×3 grid (or 2×2, panoramic rows) and download all tiles as a ZIP in posting order.

Free crop, fixed ratios and circle avatar crop — or expand the canvas with white/transparent padding to any size or ratio.

Preset canvas sizes for YouTube, Bilibili and Xiaohongshu covers — drag text over your background image, export ready to upload.

Add titles, captions, labels and text watermarks to photos — fonts, colors, outline, drag-to-place, meme and watermark presets.

Turn solid or near-solid backgrounds transparent: eyedropper color pick, tolerance slider, edge feathering, checkerboard preview, transparent PNG export.

Text or logo watermarks — nine-grid placement or full tiling, opacity/angle/density controls, batch up to 10 photos with ZIP download.

Paint over areas to pixelate or gaussian-blur them — faces, private info, license plates. Undo and redo supported.

Pick a scenario and budget tier — get flagship / balanced / budget model recommendations for video, image, voice and more.

Compare two prompts word by word — additions, removals and edits highlighted so you see exactly what changed.

Assemble structured prompts from subject, style, lighting, composition and camera — with Midjourney parameter suffixes — then copy straight into your model.

Scrub a local video, snap the exact frame to PNG/JPG, or batch-capture every N seconds into a ZIP — for thumbnails and frame-by-frame checks.

Turn a stack of images into an animated GIF — adjustable frame rate, loop and size, frame reordering, encoded locally in your browser.
