Image Optimizer — free ad image compressor

Drop in images or a banner ZIP, set a weight target, and download optimized files in seconds. Built to hit ad-server limits like 150KB initial-load and 40KB backup JPGs — without wrecking how the creative looks.

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 result and on every download.

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 to compress it. Download each image with a free account, or all as one ZIP with PRO.

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 compress them.

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 at full size with a free account — or all at once as a single ZIP with PRO.

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 with no account — a free account (no card) downloads every image at full size with no daily limit, and PRO adds Download all as one ZIP.

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. A free account downloads every Image Optimizer result at full size; Pro adds Download all. 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. Downloading needs a free account — every image at full size, with no daily limit; PRO adds Download all as one ZIP.
Do my images get uploaded to a server?
No. All compression happens locally in your browser and your files are never uploaded to do it — safe for unreleased campaigns and confidential creative. The one exception is a PRO Download all: that ZIP makes one round trip through our server so we can check the plan, then streams straight back to you — it is not stored.
Will it wreck the image quality?
It compresses intelligently: it ramps quality down only as far as needed to hit your target. The result, the preview and every download keep your original pixel dimensions wherever they can. 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. Results and downloads keep your original dimensions wherever possible. 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 with a free account, or as a single ZIP with PRO. 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; downloads need a free account and come out at full size, and $35/month (under $1 per tool) adds Download all across all 39+ 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. Use and preview every tool with no account. A free account downloads any single result at full size, with no daily limit. PRO adds Download all, every banner size, more share links and saving to your account. A few things keep a small free allowance: QA checks (2 a day with no account, 5 with a free one) and hosted share links (5 a month, 1 a day, live 3 days, each updated up to 2 times). PRO is a flat $35/month ($280/year) for unlimited use of all 39+ tools: no credit packs, no top-ups, no per-use fees. The only pay-per-use extras are optional AI work done for you, paid from the Digi Bot credit wallet: Digi Bot jobs, ✨ Ask AI in the tools, and AI drafts in Character Animation (PRO; a new account’s first draft is free) — Ask AI and AI drafts are charged for what the AI actually uses, at most 1 credit a request. Many comparable tools bill per credit (remove.bg, CloudConvert, AdCreative.ai) — here one flat subscription covers everything. See tools pricing.
