Why use it

Built to hit ad weight limits.

Any weight target

Drag the slider to any KB limit and every image is squeezed to at or under it — it opens at ~32% smaller by default.

Keeps your format

JPG stays JPG, PNG stays PNG, GIF keeps its animation, WebP stays WebP. Original dimensions on the in-app result and Premium full-size download; free downloads come at half size.

See before & after

Every image shows original vs optimized size and the percent saved, so you stay in control of quality.

Private & instant

Runs fully in your browser — nothing is uploaded — and downloads individually or as a ZIP.

How it works

Three steps, seconds, not minutes.

1

Add images or a ZIP

Drag in PNG, JPG, GIF or WebP files — or a banner .zip and we'll pull the images out. Nothing uploads to a server.

2

Set a weight target

Drag the slider to your KB limit (or type it exactly). We ramp quality down and warn you in red before any image would have to be resized.

3

Download optimized

Check the before/after on each image, then download them one at a time or as a single ZIP. Free downloads come at half size; a free login unlocks full-resolution files.

Why ours

Tuned for ad production, not just photos.

Quality-aware

It keeps quality as high as your target allows, and never ships a file bigger than the one you gave it.

Whole-banner ZIPs

Drop a banner .zip and it optimizes every image inside — handy for hitting the initial-load budget.

Real production knowledge

From a studio that builds 1,000+ trafficking-ready units a month for agencies.

What it costs

Free to use — and no session caps.

TinyPNG is excellent, and its free tier is the one most people actually hit: 20 images per session, 5 MB each. Unlimited compressions start at $39/year. Here, compressing and previewing are unlimited on the free tier — the only limit is that free downloads come out ½‑size.

Compared July 2026 from each tool’s own pricing page and interface. TinyPNG (Tinify) free tier: 20 compressions and 3 conversions per session, 5 MB per image; Web Pro is $39/yr and Web Ultra $149/yr (≈ $3.25 and $12.42 a month) — both are annual, per user. Squoosh is a free, open‑source Google project. Neither is affiliated with DigiLakshya and neither shows third‑party ads — TinyPNG is a genuinely good tool; the differences here are session caps, on‑device processing and the exact‑KB target that ad work needs. TinyIMG free downloads are ½‑size; full resolution comes with Pro. See all tools & pricing.

FAQ

Quick answers.

Is the ad image compressor free?
Yes — free to use with no signup, and it runs entirely in your browser so there's nothing to install. You can compress and preview every result in full. Free downloads are delivered at half size (a 50%-shrunk "-half" file); a free login unlocks full-resolution downloads.
Do my images get uploaded to a server?
No. All compression happens locally in your browser and your files never leave your machine — safe for unreleased campaigns and confidential creative.
Will it wreck the image quality?
It compresses intelligently: it ramps quality down only as far as needed to hit your target. The in-app result and preview — and Premium full-size downloads — keep your original pixel dimensions wherever they can; free downloads are delivered at half size. If a target is so small that an image would have to be shrunk, it warns you live — in red, by file name — so you can nudge the target up. Every image shows its before and after, and if it can't beat your original it keeps the original.
What file formats does it output?
Whatever you put in — it keeps your original format. JPG stays JPG, PNG stays PNG, GIF stays GIF (animation and all), and WebP stays WebP. Each is compressed in the way that suits it: quality for JPG and WebP, colour-depth reduction for PNG, and a palette re-encode for GIF. The in-app result and Premium full-size download keep your original dimensions wherever possible; free downloads come at half size. Drop in PNG, JPG, GIF or WebP.
Can it compress a whole banner ZIP at once?
Yes — drop in a .zip and it pulls out every image to optimize, then lets you download them individually or as a single ZIP. For high-volume optimization or full ad-server packaging done for you, see our banner resizing & production service.
How does this compare to paying for TinyPNG?
TinyPNG is a genuinely good tool — this isn't a knock on it. The practical difference is the free tier: TinyPNG caps you at 20 images per session and 5 MB per image, and unlimited compressions mean Web Pro at $39/year (about $3.25/month) or Web Ultra at $149/year (about $12.42/month) — and your images are compressed on their servers. Here, compressing and previewing are unlimited and happen entirely in your browser; the free limit is that downloads come out ½-size, and $25/month (about $1 per tool) unlocks full resolution across all 30 tools. You also get an exact-KB target (IAB 150 KB, 40 KB backup JPGs) that general-purpose compressors don't offer. Prices verified July 2026 — see the comparison above.
Do these tools use credits or tokens?
No — never. Every tool is free to use with sample or daily limits, and PRO is a flat $25/month ($199/year) for unlimited use of all 30+ tools: no credit packs, no top-ups, no per-use fees. Many comparable tools bill per credit (remove.bg, CloudConvert, AdCreative.ai) — here one flat subscription covers everything. See tools pricing.
